Hello, I am trying to get Mathematica to find the inverse of: y = 3x^3 + 2e^(2x) (which I know is invertible) InverseFunction only seems to give inverses of built-ins, like Sine. I tried: Solve[ y == 3x^3 + 2e^(2x), x ] but get a message that Solve does not have methods suitable. (Solve works for simpler functions, however.) Any ideas? Thanks.
