Homework Statement
1) Given f(x)= .01x³ + .7x -2 . Approximate ƒ−1(3).
2)Given f(x) = (x³) / (x²+1) and g(x) = ƒ–1(x). Evaluate g'(2)
The Attempt at a Solution
1) Would this be correct? 3=.01x^3 + .7x -2
But then, how would I find x at 3?
2) I am confused about going about solving this problem. Any help would be appreciated@!
Thanks
