Inverse of $$$y = 4 x$$$

Find the inverse of the function $$$y = 4 x$$$.

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: $$$y = 4 x$$$ becomes $$$x = 4 y$$$.

Now, solve the equation $$$x = 4 y$$$ for $$$y$$$.

$$$y = \frac{x}{4}$$$

$$$y = \frac{x}{4}$$$A
