Can anyone help me out for finding the inverse of this function? I'm not quite sure how to find the inverse of a polynomial...
Thank you!
Also if you can help me find this integral...
Unless you can write it in the form (which you can't - there's a point of inflexion at (-1/2, 1) but it's not a stationary point of inflexion) you'll have to solve for y using Cardano's method (see Cubic function - Wikipedia, the free encyclopedia)
