WebSo f ′ ( x) = − 4 x ( x − 1) ( x + 1) will be a product of two positive numbers and a negative number, so f ′ ( x) is negative on ( − 1, 0). That means that f ( x) is decreasing on [ − 1, 0]. Now do the same for the remaining intervals of constant sign for the derivative. You have stationary points with you (where derivative = 0 ... 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 ...
