Learn how to determine concavity and point of inflection AP style

The video tutorial explains the concept of concavity in calculus, focusing on the second derivative. It guides viewers through finding points of inflection by setting the second derivative to zero and solving for x. The tutorial also covers testing intervals to determine concavity and understanding sign changes in derivatives. The conclusion emphasizes the importance of clearly describing points of inflection and concavity changes.

What conclusions can be drawn about the concavity of a function based on the second derivative test?

What is the importance of stating the intervals of concavity when discussing points of inflection?

How do you describe a point of inflection in terms of concavity changes?
