SUMMARY
The discussion centers on proving the derivative of an inverse function using the chain rule. It establishes that if \( f^{-1} \) has a derivative, then the relationship \( (f^{-1})'(f(x)) = \frac{1}{f'(x)} \) holds true. The proof involves differentiating the composite function \( (f^{-1}(f(x)))' \) and applying the chain rule effectively. The conclusion confirms that both methods of differentiation yield consistent results, affirming the validity of the derivative relationship.
