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: $$$y = 2 x + 1$$$ becomes $$$x = 2 y + 1$$$.
Now, solve the equation $$$x = 2 y + 1$$$ for $$$y$$$.
$$$y = \frac{x}{2} - \frac{1}{2}$$$
