NOTE: you do not need the max and min part. Just watch how to make the equations and then marginal means do the derivative.

3.5 Higher derivatives

Sign charts used in 4.1-4.3

4.1 Intervals of Increase/decrease; Local max/min

4.2 Intervals of Concavity and points of inflection

4.1-4.3 Pictures/graphing everything

4.4 Absolute Max/Min

5.4 e derivatives
