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.Find step-by-step Calculus solutions and your answer to the following textbook question: Find the intervals of increase or decrease.
