Question

In the equation, f(x)=2x-4(x+1), what is the value of f(-14)?

A. 32
B. -32
C. 5
D. 24

Answer 1

D. 24

Explanation:

Plug in -14 to the equation:

f(x) = 2x - 4(x + 1)

f(-14) = 2(-14) - 4(-14 + 1)

Simplify:

f(-14) = -28 - 4(-13)

f(-14) = -28 + 52

f(-14) = 24

So, D is the correct answer.
