11-32.

If $g(x)=\sqrt{x-7}$ find $g(8)$, $g(32)$, and $g(80)$.

Substitute the given values for $x$.

$g(8)=\sqrt{8-7}=\sqrt{1}=1$

$g(32)=\sqrt{32-7}=\sqrt{25}=5$

After seeing the first two done for you, attempt the third one on your own.
If you do not get a perfect square, approximate your answer to the nearest hundredth by using a calculator.
