Concavity. Calculus-Applications of Derivatives: Optimization
Description
In the same way that critical points indicate where a function changes direction, inflection points indicate where a function changes concavity. If a function is concave down (curving downwards like a rainbow) and hits an inflection point, it'll become concave up (curving upwards like a bowl). Conversely, if a function is concave up and hits an inflection point, it'll become concave down.
