Similarly, on the righthand plot in Figure \(\PageIndex{7}\), where the function shown is concave down, we see that the tangent lines alway lie above the curve, and the slopes of the tangent lines are ...Such a curve is called a concave upwards curve. For graph B, the entire curve will lie below any tangent drawn to itself. Such a curve is called a concave downwards curve. The concavity's nature can of course be restricted to particular intervals. For example, a graph might be concave upwards in some interval while concave downwards in another.f′′(0)=0.

Concavity describes the shape of the curve. If the average rates are increasing on an interval then the function is concave up and if the average rates are decreasing on an interval then the function is concave down on the interval. A function has an inflection point when it switches from concave down to concave up or visa versa.A point of inflection is a point on the graph of \(f\) at which the concavity of \(f\) changes.
