Concavity

Definition

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.

Inflection Point: An inflection point occurs where there is a change in concavity on a graph. At this point, the graph transitions from being concave up to concave down or vice versa.

Second Derivative Test: The second derivative test helps determine if critical points on a graph represent local maxima or minima by analyzing changes in concavity.

Point of Inflection: A point of inflection is a specific type of inflection point where the graph changes concavity and has no local maxima or minima.
