The concavity of the graph of a function refers to the curvature of the graph over an interval; this curvature is described as being concave up or concave down. Generally, a concave up curve has a shape resembling "∪" and a concave down curve has a shape resembling "∩" as shown in the figure below. How to find the concavity of a function.\(f\left( x \right)\) is concave down on an interval \(I\) if all of the tangents to the curve on \(I\) are above the graph of \(f\left( x \right)\). To show that the graphs above do in fact have …Concave downward, downward, is an interval, or you're gonna be concave downward over an interval when your slope is decreasing.

It explains how to find the inflections point of a function...An inflection point requires: 1) that the concavity changes and. 2) that the function is defined at the point. You can think of potential inflection points as critical points for the first derivative — i.e. they may occur if f"(x) = 0 OR if f"(x) is undefined. An example of the latter situation is f(x) = x^(1/3) at x=0.
