WebYes, however, finding the inverse of a cubic function is very difficult. You can find the inverse of a quadratic function by completing the square. Finding the inverse of a simple cubic function, for example, f(x) = x^3 is easy. But finding the inverse of f(x) = x^3 + 5x^2 + 2x - 6 is very difficult, if not impossible.
