WebAug 2, 2024 · Fine the intervals on which the function f(x)= ax^2 +bx+c (where “a” doesn’t =0) is increasing and decreasing. ... Obviously if X is the x coordinate of the vertex, the function will be decreasing on (-∞,X) and increasing on (X,+∞). The other case, a<0, ... WebThe idea of increasing or decreasing functions is related to having environments or intervals where the function is increasing or decreasing. A function will have different parts, some of them increasing and/or decreasing. Now we will study these intervals using the derivatives.

WebIncreasing/Decreasing Functions. The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′ (x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′ (x) < 0 at each point in an interval I, then the function is said to be ...
