Step 2: Use the table below to test the regions to see where the function increases or decreases. Include your work for determining the sign of each interval. Intervals Sign of f'(x) Behavior of f (x) (Steps continued on the next page) Step 3: Find the possible inflection points and plot them on the graph below. a. Find the second derivative. b. Set the second derivative equal to 0 and find where the second derivative does not exist. c. Plug the x-value of each possible point of inflection into the original O O function to find the y-value of the point itself. O
