If h = x ^ 2 find h^ -1

To find the inverse of a function h, you need to switch the roles of x and h and then solve for x.

Given h = x^2, we want to find h^ -1 such that h^ -1 = f^ -1(h).

Let y = x^2, then x = ±√y. The inverse function is obtained by replacing x with y, and vice versa.

Therefore, h^ -1 = ±√h
