Calculus I: Finding Intervals of Concavity ...Our definition of concave up and concave down is given in terms of when the first derivative is increasing or decreasing. We can apply the results of the previous section to find intervals on which a graph is concave up or down. That is, we recognize that \(\fp\) is increasing when \(\fpp>0\text{,}\) etc. Theorem 3.4.4 Test for Concavity 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 this function f f is concave down.

7 years ago. Concavity and convexity are opposite sides of the same coin. So if a segment of a function can be described as concave up, it could also be described as convex down. The graph of a function f is concave down when f ′ is decreasing. That means as one looks at a concave down graph from left to right, the slopes of the tangent lines will be decreasing. Consider Figure 3.4.1 (b), where a concave down graph is shown along with some tangent lines.

A concave down graph is shaped like an upside down U (“⋒”). They tell us something about the shape of a graph, or more specifically, how it bends. That kind of information is useful when it ... Details. To visualize the idea of concavity using the first derivative, consider the tangent line at a point. Recall that the slope of the tangent line is precisely the derivative. As you move along an interval, if the slope of the line is increasing, then is increasing and so the function is concave up. Similarly, if the slope of the line is ... Sep 28, 2023 · The fact that its derivative, \(f'\text{,}\) is decreasing makes \(f\) concave down on the interval. Figure \(\PageIndex{7}\).
