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.
Work through problems 1-9 and 19 for Exercise 5.4. When you are done, check your answers against Appendix A.
