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

The answer is 8

Step-by-step explanation:

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

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

Answer is C

Step-by-step 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

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

560

hope this : )
