(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Assume f ^-1 (inverse) has a derivative. Use the chain rule to prove that

(f^-1)' (f(x)) = 1/f'(x)

2. Relevant equations

No real equations other than definition of chain rule.

3. The attempt at a solution

I'm not sure how to start other than with the definition of (f^-1) (f(x)) = x
