Example of strictly increasing function

WebRemark 4. The reverse statement is not true. For example, f(x) = x3 is a strictly increasing function with its derivative 0 at x= 0. One can modify this statement by the following one: fis a non-decreasing function on [a;b] if and only if f0 0 on (a;b). 23. f(1) = 10, f0(x) 2. You may try to guess if f is a line with slope 2, then f(4) = WebDecreasing Function in Calculus. For a function, y = f (x) to be monotonically decreasing (dy/dx) ≤ 0 for all such values of interval (a, b) and equality may hold for discrete values. Example: Check whether the …
