f%28x%29=-3x-2

1. Replace f%28x%29 with y.
y=-3x-2


2. Reverse the roles of x and y, that is replace every occurrence of x with y and every occurrence of y with x.
x=-3y-2


3. Solve for y in terms of x.
3y=+-x-2

y+=+%28-x-2%29%2F3


4. Replace y with f%5E-1%28x%29.

f%5E-1%28x%29=+%28-x-2%29%2F3
