relative rate of change

Question: If $y = x^x$ find the relative rate of change of y with respect to x when x = 1.

How do I go about answering this question?

You derive the equation, the derivate is the relative rate of change.

oh thats it! thank you so much
Answer would be: $X^x (ln x + 1)$ correct?
