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.

WebThe inverse function is x = 4 + 2y^3 + sin ( (pi/2)y) => 0 = 2y^3 + sin ( (pi/2)y) since x=4. Therefore y=0. So the coordinate for the inverse function is (4, 0) and the non-inverse function (0, 4) So you choose evaluate the expression using inverse or non-inverse function Using f' (x) substituting x=0 yields pi/2 as the gradient.
