WebAug 24, 2016 · 👉 Learn how to determine increasing/decreasing intervals. There are many ways in which we can determine whether a function is increasing or decreasing but w... WebSolution: f ′ ( x) = 3 x 2 − 6 x = 3 x ( x − 2) Since f ′ is always defined, the critical numbers occur only when f ′ = 0, i.e., at c = 0 and c = 2. Our intervals are ( − ∞, 0), ( 0, 2), and ( 2, ∞). On the interval ( − ∞, 0), pick b = − 1 . (You could just as well pick b = − 10 or b = − 0.37453, or whatever, but − 1 ...
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 ... WebSplit into separate intervals around the values that make the derivative or undefined. Step 5 Substitute a value from the interval into the derivative to determine if the function is …
