f ′ can only change sign at a critical number. The reason is simple. If f ′ (x) is continuous and it changes sign, then it has to pass through 0 on its way from negative to positive (or vice versa ). That's the Intermediate Value Theorem. If f ′ (x) is not continuous where it changes sign, then that is a point where f ′ (x) doesn't exist.

We see that the derivative will go from increasing to decreasing or vice versa when #f'(x) = 0#, or when #x= 0#. Whenever you have a positive value of #x#, the derivative will be positive, therefore the function will be increasing on #{x|x> 0, x in RR}#. The graph confirms . Hopefully this helps!
