To find the inverse of the function $f(x) = 16 - \frac{(x-5)^2}{4}$, follow these steps:

1. Rewrite the function with $y$ in place of $f(x)$: $y = 16 - \frac{(x-5)^2}{4}$

2. Solve for $x$ in terms of $y$:

   $y = 16 - \frac{(x-5)^2}{4}$

   Subtract 16 from both sides:

   $y - 16 = -\frac{(x-5)^2}{4}$

   Multiply both sides by -4:

   $-4(y - 16) = (x-5)^2$

   Simplify the left side:

   $4(16 - y) = (x-5)^2$

   Take the square root of both sides:

   $\sqrt{4(16 - y)} = x - 5$

   $2\sqrt{16 - y} = x - 5$

   Add 5 to both sides:

   $x = 5 + 2\sqrt{16 - y}$

3. Interchange $x$ and $y$ to write the inverse function:

   $y = 5 + 2\sqrt{16 - x}$

4. Write the final form of the inverse function:

   $f^{-1}(x) = 5 + 2\sqrt{16 - x}$

The inverse function of $f(x) = 16 - \frac{(x-5)^2}{4}$ is:

$f^{-1}(x) = 5 + 2\sqrt{16 - x}$
