need some help on finding the critical value and x intercept of this equation:
y(x) = ax-xln(x)
thanksness
A critical value would be a value where the first derivative of the function is 0 or where the function does not exist.
So the function does not exist at x = 0, so this is a critical point.
So when this is 0 we have a critical point:
So this is your other critical point.
