CPM Homework Help : PC3 Problem 9-36

For each of the following functions, restrict its domain (if necessary) so that it is invertible. Then write an equation for the inverse.

$g(x) = 5(x − 2)^2$
Hint (b):
This curve is a parabola. When reflected across the line $y = x$ , it will not be a function. Restrict the domain so that the reflected curve will be a function.
