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: $$$y = 16 x^{2} + 1$$$ becomes $$$x = 16 y^{2} + 1$$$.

Now, solve the equation $$$x = 16 y^{2} + 1$$$ for $$$y$$$.

$$$y = - 4 \sqrt{x - 1}$$$

$$$y = 4 \sqrt{x - 1}$$$

Answer

$$$y = - 4 \sqrt{x - 1}$$$A

$$$y = 4 \sqrt{x - 1}$$$A
