Increase decrease interval calculator - 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 ...
