Learn how to determine concavity of a polynomial function

The video tutorial explains how to determine concavity and identify possible points of inflection using the second derivative. It covers the process of finding the second derivative, testing intervals for concavity, and using test points to analyze concavity. The tutorial concludes with a justification of the identified inflection points.

What conclusions can be drawn about the concavity of the function on the intervals identified?
