8-77.

Find the inverse functions below. Homework Help ✎

If

*f*(*x*) = 2*x*− 3, then what does*f*^{−}^{1}(*x*) equal?If

*h*(*x*) = (*x*− 3)^{2}+ 2 for*x*≥ 3, then what does*h*^{−}^{1}(*x*) equal?

Rewrite the equation as *y* = 2*x* − 3. Then switch *x* and *y* and solve for *y*.

*x* = 2*y* − 3

Solve for *y*.
