## Whitman College: David Guichard's "Calculus, Chapter 5: Curve Sketching, Section 5.4: Concavity and Inflection Points"

Read Section 5.4 (pages 109 and 110). In this reading, you will see how the second derivative relates to concavity of the graph of a function and use this information to find the points where the concavity changes, i.e. the inflection points of the graph.
