   What is the concavity test of a function?

   • The concavity test of a function is used to determine the concave nature of a function's graph. It relies on the second order derivative of the function. The function can be concave upward or concave downward.

   What is the sense of concavity of a function?

   • The concavity of a function, or more precisely the sense of concavity of a function, describes the way the derivative of the function is changing. There are two determinate senses of concavity: concave up and concave down. Note that it is possible for a function to be neither concave up nor concave down.

   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.
