WebThe definitions for increasing and decreasing intervals are given below. For a real-valued function f(x), the interval I is said to be an increasing interval if for every x < y, we have f(x) ≤ f(y).; For a real-valued function f(x), the interval I is said to be a decreasing interval if for every x < y, we have f(x) ≥ f(y).
