CPM Homework Help : PC3 Problem 5-126

Given $f(x)=4x+2$ , $g(x)=10x^2-8$ , and $h\left(x\right)=\sqrt{x}+2$ , write equations for:

$f(g(−2))$
Hint (a):
Evaluate $g(−2)$ first. Then substitute that value into the $f$ function.

$h^{−1}(x)$
Hint (c):
1. Let $h(x)=y$ . Switch the $x$ and $y$ .
2. Solve for $y$ .
