Question

If f(x) = (-x)^3, what is f(-2)?
-6
-8
8
6

Answer 1

-(-2)^3 = 2^3 = 8

Answer is C

Explanation:

So we plug in the numbers. We have -2 as x. (-(-2)^3 would be our thing. Thats because our x is the negative so the negative of -2 is 2.

2^3 = 8

therefore its 8

Answer 2

The answer is 8

Explanation:

Plug -2 in for x. The double-negative inside the parenthesis makes it positive, then do the exponent.
