Question

If the domain of the function f(x)=3x - 4 is {-2 ≤ x ≤ 3}, which of the following integers is not in the range of the function?

A) -7
B)-4
C)8
D)5
E)-10

Answer 1

The integer that is not in the range of the function is C) 8.

Which integer is not in the range of the function?

From the question, we have the following parameters that can be used in our computation:

f(x) = 3x - 4

Also, we have

Domain = {-2 ≤ x ≤ 3}

using the above as a guide, we have the following:

Minimum = 3 * -2 - 4 = -10

Maximum = 3 * 3 - 4 = 5

The number 8 is not in the range -10 to 5

Hence, the integer that is not in the range of the function is C) 8.
