Use this information to determine whether [latex]f[/latex] has any inflection points. The second derivative can also be used as an alternate means to determine or verify that [latex]f[/latex] has a local extremum at a critical point.Study Tips. The Second Derivative Test for Concavity. Here we will learn how to apply the Second Derivative Test, which tells us where a function is concave upward or downward. Concavity is simply which way the graph is curving - up or down. It can also be thought of as whether the function has an increasing or decreasing slope over a period.David Guichard (Whitman College) Integrated by Justin Marshall. 4.4: Concavity and Curve Sketching is shared under a not declared license and was authored, remixed, and/or curated by LibreTexts. We know that the sign of the derivative tells us whether a function is increasing or decreasing; for example, when f′ (x)>0, f (x) is increasing.Subject classifications.
