The derivative of that function is
y ' = (ln x + 1)*x^x
I will provide a website with the derivation separately.
I don't know what you mean by the "turning point of the function y-x^x". That function would always be zero. Do you mean the minimum of the function y = x^x?
See this website for how to differentiate the function:
