Question

Given f(x)= -2x -13, what is f(-3) -7?

A: -26
B: -14
C: -7
D: 0
E: 26

Answer 1

B: -14

Explanation:

given that f(x) = -2x - 13,

we can find the value of f(-3) by simply plugging in -3 for x

f(-3) = -2(-3) - 13

f(-3) = -7

Because we are dealing with the expression f(-3) - 7, we still have one more step. Let's plug in -7 for f(-3)

- 7 - 7 = -14

Therefore, f(-3) - 7 will give us B: -14
