Nothing appears. Attach the picture to your post instead. You should always make an attempt, and show your work.

How is the derivative of the inverse function $x = f^{-1}(y)$ related to the derivative $f'(x)$?

Use the inverse function theorem.

You posted a link to an attachment in your gmail account. We can't read it. Instead, host the media somewhere public and provide that link. Or just tell us what the problem is.

In fact, the very act of precisely describing a question, often sparks the solution. Because to even ask the question you have to grapple with the concepts and the notation.

So as a start, why not just describe the problem in words and symbols?
