Question

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

Answer 1

Firstly, substitute the given value of x.

$f(x) = ( - x)^{3} \\ f( - 2) = ( - ( - 2))^{3}$
Next, distribute the negative sign. Like signs make a positive value.
$( - ( - 2)) = 2$
Lastly, solve the exponent.

$2 ^{3} = 8$
Therefore:
$f( - 2) = 8$

Answer 2
