If f' changes signs from negative to positive around a critical number c, then what happens? Of has neither a local max nor local min at c. O Then f has a point of inflection at c O Then f goes from decreasing to increasing and therefore f has a relative minimum at c. O Then f goes from increasing to decreasing and therefore has a relative max at c.
