Find the inverse functions below.

1. If $f\left(x\right) = 2x − 3$, then what does $f ^{−1}(x)$ equal?

   Hint (a):

   $x = 2f ^{−1}\left(x\right) − 3$
   Solve for $f ^{−1}\left(x\right)$.

   Answer (a):

   $f^{-1}(x)=\frac{{x+3}}{2}$

2. If h(x) = (x − 3)² + 2, then what does h⁻¹(x) equal?

   Hint (b):

   See part (a).

   Answer (b):

   $h^{-1}(x)=\sqrt{x-2}+3$
