f%28x%29=+3-2x Start with the given equation


y=+3+-2x Replace f%28x%29 with "y"


x=+3+-2y Switch "x" and "y". The goal now is to solve for "y"


x-3=-2y Subtract 3 from both sides.


%28x-3%29%2F%28-2%29=y Divide both sides by -2 to isolate "y"


%28-x%2B3%29%2F%282%29=y Simplify


So the solution is y=%28-x%2B+3%29%2F%282%29 which means that the inverse function is
