Derivative of a polynomial function
http://web.mit.edu/wwmath/calculus/differentiation/polynomials.html WebHere is what I have so far: Let f ( x) = x 5 + 2 x 3 + x − 1. a) Find f ( 1) and f ′ ( 1) I have a) done. f ( 1) is 3 and f ′ ( 1) is 12. b) Find f − 1 ( 3) and ( f − 1) ′ ( 3) I need help with the first part. I think the way to find the inverse is to switch the x 's with y 's and then solve for y. But I am having trouble completing ...
