WebThus, since the derivative increases as x x increases, f ′ f ′ is an increasing function. We say this function f f is concave up. Figure 4.34(b) shows a function f f that curves downward. As x x increases, the slope of the tangent line decreases. Since the derivative decreases as x x increases, f ′ f ′ is a decreasing function. We say ... WebSolution : The function is increasing on [0, 25] and [35, 40]. It is decreasing on [40, 50]. The function is constant (neither increasing nor decreasing) on [25, 35] and [50, 80]. This means that the person gained weight until age 25, then gained weight again between ages 35 and 40. He lost weight between ages 40 and 50.

Using the First Derivative to Identify Increasing & Decreasing Functions

WebSep 18, 2024 · A derivative is positive when the original function is increasing, and negative when the original function is decreasing. So you look at where the original function increases and decreases to tell you when the derivative is positive or negative. ... We have … WebA function with this property is called strictly increasing (also increasing). Again, by inverting the order symbol, one finds a corresponding concept called strictly decreasing … Web9/20/2024 ALEKS … 1/2 Student Name: Student RandyAHwaier Date: 09/20/2024 Graphs and Functions Finding where a function is increasing, decreasing, or constant given the graph: Interval notation Determine the interval(s) on which the function is (strictly) increasing.
