WebDec 28, 2024 · Figure 9.32: Graphing the parametric equations in Example 9.3.4 to demonstrate concavity. The graph of the parametric functions is concave up when \(\frac{d^2y}{dx^2} > 0\) and concave down when \(\frac{d^2y}{dx^2} <0\). We determine the intervals when the second derivative is greater/less than 0 by first finding when it is 0 or … WebSep 7, 2024 · For f(x) = − x3 + 3 2x2 + 18x, find all intervals where f is concave up and all intervals where f is concave down. Hint. Answer. We now summarize, in Table 4.5.4, the information that the first and second derivatives of a function f provide about the graph of f, and illustrate this information in Figure 4.5.8.

WebTo determine the concavity of ,recall that is concave up when is increasing and is concave down when is decreasing. From the graph, we see that is increasing on the interval , and decreasing on the interval . Hence, the … WebTo some degree, the first derivative can be used to determine the concavity of f (x) based on the following: If f' (x) is increasing over an interval, then the graph of f (x) is concave … WebA curve that is shaped like this is called concave up. Figure 4.4. 1: f ″ ( a) > 0: f ′ ( a) positive and increasing, f ′ ( a) negative and increasing. Now suppose that f ″ ( a) < 0. This means … f key to share screen
