Solution
To find the inverse function, swap $$$x$$$ and $$$y$$$, and solve the resulting equation for $$$y$$$.
This means that the inverse is the reflection of the function over the line $$$y = x$$$.
If the initial function is not one-to-one, then there will be more than one inverse.
So, swap the variables: $$$y = x^{2} + 16$$$ becomes $$$x = y^{2} + 16$$$.
Now, solve the equation $$$x = y^{2} + 16$$$ for $$$y$$$.
$$$y = \sqrt{x - 16}$$$
$$$y = - \sqrt{x - 16}$$$
