Use x,y format.
y=%28x%2B1%29%2F%28x%2B3%29
Now interchange x and y and solve for y.
This new y will be the inverse function.
highlight%28x%29=%28highlight%28y%29%2B1%29%2F%28highlight%28y%29%2B3%29
x%28y%2B3%29=y%2B1
xy%2B3x=y%2B1
xy-y=1-3x
y%28x-1%29=1-3x
y=%281-3x%29%2F%28x-1%29
highlight%28f%5E%281%29=%28-3x%2B1%29%2F%28x-1%29%29
