- TL;DR Summary
- There's a simple method for finding an inverse function of a quadratic function.But I wonder whether an inverse function of a special cubic function can be found.

Like this one: ##f(x)=3x^3 -18x^2 +36x##.Is there any way to find the inverse of this function without using the general solution to cubic equation?
