Determine increasing and decreasing intervals
WebDerivatives can be used to determine whether a function is increasing, decreasing or constant on an interval: f(x) is increasing if derivative f′(x) >0, f(x) is decreasing if derivative f′(x) <0, f(x) is constant if derivative f′(x) = 0. A critical number, c, is one where f′(c) = 0 or f′(c) does not exist; a critical point is (c,f(c ...

WebDec 20, 2024 · If a function is decreasing and concave up, then its rate of decrease is slowing; it is "leveling off." If the function is increasing and concave up, then the rate of increase is increasing. The function is increasing at a faster and faster rate. Now consider a function which is concave down.
WebIf f′(x) > 0, then f is increasing on the interval, and if f′(x) < 0, then f is decreasing on the interval.
