f(x)=6x^3-3

1.  Replace f(x) with y:  y = 6x^3 - 3   
2.  Interchange x and y:  x = 6y^3 - 3       x+3                                      x+3
3.  Solve this result for y:    y^3 =           ---------   or y = cube root of  -------
                                 -1                                6                                          6
4.  Replace y with  f     (x)
