Example 7: Finding the Intervals of Increase and Decrease of a Rational Function. Determine the intervals on which the function 𝑓 (𝑥) = 7 𝑥 𝑥 + 9 is increasing and where it is decreasing. Answer . To establish intervals of increase and decrease for a function, we can consider its derivative, 𝑓 ′ (𝑥).How to Find Increasing and Decreasing Intervals. Given a function, f (x), we can determine the intervals where it is increasing and decreasing by using differentiation and algebra. Step 1: Find the derivative, f' (x), of the function. Step 2: Find the zeros of f' (x). Remember, zeros are the values of x for which f' (x) = 0.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 ...Using the derivative to reason about intervals of increase and decrease.
