    f(x) = 3 log(x + 2)  –  4

                                    y = 3 log(x + 2)  –  4

                                y + 4 = 3 log(x + 2)

                          (y + 4) ⁄ 3 = log(x + 2)

                   10^[ (y + 4) ⁄ 3 ] = x + 2

            10^[ (y + 4) ⁄ 3 ]  –  2 = x

    f   ‾  ¹  (x) = 10^[ (x + 4) ⁄ 3 ]  –  2
