1-138.

Evaluate each expression given the functions described in the tables below.

 $x$ 0 7 6 5 3 $g(x)$ 9 –1 0 3 8
 $x$ 3 0 12 4 8 $h(x)$ 2 8 –2 12 10
1. $h(g(5))$

$g(5)=3$

1. $g^{-1}(0)$

Determine the input for $g$ that gives an output of $0$.

1. $h(h(4))$

$h(4)=12$, so determine $h(12)$.

1. $g(h^{-1}(8))$

$h^{−1}(8)=0$ (Why?)
