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.
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.
