8-86.

Find the equation for the inverse of the function $f ( x ) = 2 \sqrt { \frac { ( x - 3 ) } { 4 } } + 1$ Sketch the graph of both the original and the inverse.

To find the inverse, change every x to f(x) and every f(x) to x. Solve for f(x).

If you found a few points for the graph of f(x), how can that help you graph the inverse equation?
