WebFigure 1. Both functions are increasing over the interval (a, b). At each point x, the derivative f(x) > 0. Both functions are decreasing over the interval (a, b). At each point x, the derivative f(x) < 0. A continuous … WebIf a function is decreasing and concave up, then its rate of decrease is slowing; it is “leveling off.” You can see this in the left side of Figure 3.4.2. 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.
