1. 2.1

2.  Remember that the first derivative test will tell where a function is increasing or decreasing.

3.  Use the first derivative test to determine intervals of increase/decrease  Use the second derivative test to determine intervals of concave up/down

4.  Concavity is the “bend” of the graph  Concave up –-  Concave down--

5.  Points of Inflection- Similar to critical points. This is where a function changes from concave up to concave down.  Find the second derivative and find where it is equal to zero or is undefined  These are possible points of inflection

6.  Perform the first and second derivative test on and determine the intervals of increase/decrease and concave up/down.

7.  Perform the first and second derivative test on to determine intervals of increase/decrease and concave up/down.

8.  Find all points of inflection as well as all intervals of concave up/down in the function on the interval [ ]

9.  Pg 228 #31-45 odd find interval of increase/decrease and concave up and down
