Find the inverse of f(x)=2x-3.

1) replace "f(x)" with "y."   Then y=2x-3.
2) interchange x and y.  Then x=2y-3.                   x+3
3) solve this result for y.  Then 2y=x+3, or   y=----------------

                            -1           -1           x+3                        
4) replace y with f   (x):    f    (x) = ---------
                                                           2
