Intervals of increase and decrease calculator.

To establish intervals of increase and decrease for a function, we can consider its derivative, 𝑓 ′ (𝑥). If 𝑓 is differentiable on an open interval, then 𝑓 will be increasing on intervals where 𝑓 ′ (𝑥) > 0 and decreasing on intervals where 𝑓 ′ (𝑥) 0. Let’s begin by checking that the function 𝑓 (𝑥) is ..., hence the interval is an interval of decrease. Choose a value in the second interval, say 1. , hence the interval is an interval of increase. This is an even-degree polynomial with a positive lead coefficient, hence both ends take off to positive infinity.
