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:
$f( - 2) = 8$

If one quart is the same amount as 2 pints, how many pints are in 8 quarts

arsen [322]

1 quart = 2 pints.
2 quarts= 4 pints
4 quarts= 8 pints
6 quarts = 12 pints
8 quarts = 16 pints

or you could take 8 x 2= 16 pints
