Why we can use the second derivative to find points of inflection. What is concavity, and what is a point of inflection.  Second derivative test and a complete analysis of a quartic function, including intervals of concavity, intervals of increase and decrease.  LOTS of good stuff here!  AND the last piece of the puzzle for complete curve sketching skills.  EASY PEASY!
