It's easy to show that when so it must be one to one.
I don't know where to start with this one:
f(x) = the integral from 1 to x of square root of (1+t^3) for x greater than or equal to -1
I need to show that it's one to one and then find f^-1 of 0
(Sorry for the formatting, I don't know how to get the formulae and whatnot)
