For the last one are supposed to find the inverse of just show that an inverses exisis?
Here is a link to the general cubic formula( like the quadratic, but for degree 3 equations)
The Cubic Formula
Good luck
mmm... i messed up on the integral... was supposed to be , im tryna figure out the integral, coming out with a numerical answer, not if it goes to infinity..
and for the last one, im trying to find the inverse, so i switched y and x, then i have to solve for y
this is all i got...
