WebHow to Find Where a Function is Increasing, Decreasing, or Constant Given the Graph. Step 1: A function is increasing if the y y values continuously increase as the x x values … WebApr 4, 2024 · We use a derivative of a function to check whether the function is increasing or decreasing. Suppose a function f(x) f ( x) is differentiable on an open interval I I, then we have: If f′(x) ≥ 0 f ′ ( x) ≥ 0 on I I, the function is said to be an increasing function on I I. If f′(x) ≤ 0 f ′ ( x) ≤ 0 on I I, the function is said to ...
