CPM Homework Help : INT3 Problem 8-16

What is the inverse of each function given below?

$f\left(x\right) = 2x - 3$
Hint (a):
This function multiplies by $2$ and then subtracts $3$ . How can those operations be undone?
Answer (a):
$f^{-1}(x) = \frac{x + 3}{2}$

$h\left(x\right) = \left(x - 3\right)^{2} + 2$ for $x ≥ 3$
Hint (b):
List out the operations (in order) of the original function. Then "undo" them.
Answer (b):
$h^{-1}(x) = \sqrt{x - 2} + 3$
