  • Algebra and Functions Questions

 Question # 1



Which of the following statements is true for this formula?

A. When the value of b is greater than 2, a is negative.

B. When the value of b is less than 2, a is positive.

C. When the value of b is less than -2, a is negative.

D. When the value of b is greater than -2, a is negative.


The answer is (C).

If a = ½ b + 1, then a = 0 when b = -2. Thus, a > 0 when b > -2 and a < 0 when b < -2. Only answer (C) supports this conclusion.

Therefore, the correct answer is (C).


Question # 2

Which of the following answers is equal to:





The answer is - (D).

Identify like terms:

Rearrange terms so that like terms are together:

Combine the like terms:


Therefore, the answer is (D).

You probably did not combine the like terms correctly if you chose any other answer.


Question # 3



What is the equation of the line in the graph above?

A. y = 2x -4

B. y = -2x + 4

C. y = -4x + 2

D. y = 4x + 2


The answer is (A).

Remember the following formula:
The line equation is: 
the intersection point of the line and the y axis.
You can infer from the sketch that the line intercepts the axis when: .

1.The intercept points of the function and the x and y axis are: .

Find the slope of the function:

Find the equation of the line:

Accordingly, the answer is (A).

If you chose answer (B) or answer (C), review your calculations, especially the slope formula. If you chose answer (D), review your calculations, especially the line equation definitions.


Question # 4


A. Between 0 and 1.

B. Between 1 and 2.

C. Between 2 and 3.

D. Equal to 1.



The answer is (B).

Method A:

In order to understand the range of the expression, evaluate the numerator and denominator separately:

To simplify, assume the following formula  

In this expression, the numerator is greater than the denominator: ;

Therefore, the fraction is greater than , so you can eliminate answers (A) and (D).

Next, evaluate whether the expression is between  and  or and , by evaluating :the numerator  is smaller than the denominator ; this makes the fraction less than .
Now, evaluate the fraction is always less than .

Method B:

Another way to solve this is to substitute numbers into the unknowns.
Note: the substitution has to fit the data given in the question.

, thus substitute 

, thus substitute 

, thus substitute 

The expression is between  and ; therefore, the correct answer is (B).

If you chose any other answer, review the explanation and the definition of fractions.


Question # 5



A. 20

B. 4

C. -1

D. -2

D. N


The answer is (C) - (-1).

This question deals with a single variable equation. 
When solving a single variable equation, the goal is to isolate the variable (mostly called x) to find its value.
The way to do that is by gathering all variable-expressions of the equation (one or more X-expressions) on one side and all numerical members of the equation on the other side. This is done using the four operations (+, -, *, /) in the equation, as needed.
Important! Any numerical operation must be applied on both sides of the equation.
On this case, to isolate X apply the following operations to both sides of the equation:
15 + 3X - 6 = 7X + 11- 2X
9 + 3X = 5X + 11
1. Subtract 3X
9 + 3X - 3X = 5X + 11 - 3X
9 = 2X + 11
2. Subtract 11
9 - 11 = 2X + 11 - 11
-2 = 2X
3. Divide by 2
-2/2 = 2X/2
=> -1 = X


Question # 6



Which of the following statements is true?

A. Element A is greater than element B.

B. Element B is greater than element A.

C. Element A is equal to element B.

D. There is not enough information to determine the answer.


The answer is (B).

Note that  is positive.

The value of  is squared, so it must be positive.

Therefore, the answer is (B).

If you chose any other answer, you probably did not reduce correctly.



  • Number Series Questions


Question # 7

What would be the next number in the following series?

3 | 3 | 3 | 6 | 3 | 9 | 3 | ?

A. 3

B. 27

C. 12

D. 6


The answer is (C) - 12

There are two ways to look at this series:
(1) There are two inner series. each following a different rule:
Odd terms- remain constant: 3. 
Even terms- increase by 3: 
3+3=6, 6+3=9, 9+3=12.

(2) Another point of view: 

The series in this question follows two rules:
(1) The mathematical operations between the terms change in a specific order, x, : and so forth.
(2) Every two steps the number by which the terms are multiplied or divided increases by 1.


Question # 8

What would be the next number in the following series?

7 | 14 | 28 | 32 | 64 | 128 | ? | ?

A. 257|1128

B. 208|514

C. 132|264

D. 340|686


The answer is (C) - 132 | 264.

The series repeatedly increases by x2, x2, +4.


How To Ace the IBEW Math Test?

The IBEW electrical aptitude test and especially the math section in it is considered more difficult than other common pre-apprenticeship tests.

The mathematical concepts required in this Electrical Aptitude Test (functions, polynomials, etc.) are more complex than those found in nearly all apprenticeship tests. Therefore, this preparation includes an emphasis on the math section.

This test measures your proficiency in obtaining information from a given text.


Question #9

A coronary stent is a metal tube placed in the coronary arteries to keep them open to treat coronary heart disease. The cardiologist uses a projectional radiographer to assess the location and estimate the blockage's size by injecting a contrast medium through the guide catheter and viewing blood flow through the downstream coronary arteries. Intravascular ultrasound may be used to assess the lesion's thickness and hardness. The cardiologist uses this information to decide whether to treat the lesion with a stent.

How many electrical medical instruments may the cardiologist use?

A. One

B. Two

C. Three

D. Four


The answer is (B) - Two.

Notice the question referring to electrical Instruments: "The cardiologist uses a projectional radiographer to assess the location and estimate the blockage size by injecting a contrast medium through the guide catheter and viewing the flow of blood through the downstream coronary arteries. Intravascular ultrasound may be used to assess the lesion's thickness and hardness." – that is, TWO electrical instruments.


Question #10

Recruiters spend their time building relations with prospective employees or people who could refer them to talent. Social media, in general, has increased the ability to develop and maintain connections with people. Since social media has proved to accelerate relationships and knowledge of these relationships, that information can be better used to support all human resources needs. Social tools can be used to manage compensation, benefits, acquiring talent, grooming talent, aligning employee success with business success, matching like-minded employees, and cultivating innovation within the organization.

How can social media tools be employed in HR departments?

A. Compensate workers in case of loss of competencies

B. Developing innovative applications for social networks

C. Recruiters can be referred to potential talents

D. Further investigate people's privet life for matching


The answer is (C).

According to the passage: "Recruiters spend their time building relations with prospective employees or people who could refer them to talent. Social media, in general, have increased the ability to build and maintain relations with people." So social media can assist in the task of referring new talent. Answer (A) is incorrect. Although compensation is mentioned in the passage, it does not say anything about the loss of competencies. (B) and (D) are not mentioned in the passage at all.


How To Ace the IBEW Reading Comprehension Test?

You can study for the Verbal Comprehension section of the NJATC Electrical Aptitude test (The National Joint Apprenticeship and Training Committee) even when you are not actively preparing. How?

How To Ace the IBEW Aptitude Test?

The standard passing score of the IBEW aptitude test is 4/9. However, getting the bar score doesn’t necessarily mean you’ll get an internship since open apprenticeships programs are limited and demand consistently exceeds supply. Eventually, the IBEW will select the candidates with the highest scores to continue the process, so just passing is not enough. Therefore, for optimal test performance that will grant you with NJATC internship, it’s better to prepare appropriately and rise above the competition.

Using an accurate and proven practice plan that includes full-length IBEW practice test simulations of the actual test will eliminate the guesswork and enhance your chances of scoring high.
