Question

find the derivative of the function y=x^x

Hence fin the coordinates of the turning point of the funcion y-x^x. Give the values correct to two decimal places

Answer 1

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?

Answer 2

See this website for how to differentiate the function:
