     • Concavity describes whether a graph opens upward (concave up) or downward (concave down). It indicates whether the graph is curving upwards like an "U" shape or downwards like an "n" shape.

   How do you find the concavity of a function?

   • At these points, the sign of f" (x) may change from negative to positive or vice versa; if it changes, the point is an inflection point and the concavity of f (x) changes; if it does not change, then the concavity stays the same. Given these facts, we can now put everything together and use the second derivative of a function to find its concavity.

   Why do we need to know where a graph is concave?

   • If we are trying to understand the shape of the graph of a function, knowing where it is concave up and concave down helps us to get a more accurate picture. Of particular interest are points at which the concavity changes from up to down or down to up; such points are called inflection points.

   How do you know if a function is concave?

   • In mathematical terms, a function f(x) f (x) is concave up on an interval if the second derivative f′′(x) f ′ ′ (x) is positive at each point of the interval and concave down if it is negative at each point of the interval. If none of the conditions are met, the function is considered neither concave up nor concave down on that interval.

   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. Concave up.
