Web2. Even Mathematica can't find inverse function, but you can be confident - inverse function does exist. – Norbert. Oct 10, 2012 at 21:42. 10. Your polynomial is increasing, and its range is all reals, so there is an inverse. Finding a pleasant expression for the inverse is another matter. But one can find information about the derivative of ... WebAnd a function maps from an element in our domain, to an element in our range. That's what a function does. Now the inverse of the function maps from that element in the range to the element in the domain. So that over there would be f inverse.
