WebMar 8, 2024 · First, show that f is (weakly) decreasing. Take any points x 1 < x 2 in the interval [ a, b]. By the mean value theorem, there exists a c ∈ ( x 1, x 2) such that f ( x 2) − f ( x 1) x 2 − x 1 = f ′ ( c) ≤ 0 Hence, f ( x 2) ≤ f ( x 1), and f is decreasing in [ a, b]. WebA function f is called strictly decreasing, if for all numbers a and b satisfying a < b , we have f ( a) > f ( b) . If the function f is not defined for all numbers, then we only require that this happens for all numbers a, b for which f ( a) and f ( b) are defined. The definition is otherwise the same as for strictly increasing, but the sign ... does chandler have a girlfriendWebOne way to ensure that a function has a strictly decreasing derivative is strict concavity : a function is strictly concave if equality is reversed in the definition of strict convexity and the proof is similar.
