2. The graph of the derivative a function f (domain x E R ) is shown below. y = f (x) -5 -4 -3 - R 3 5 Use the graph to assist you in answering the following questions. If you are estimating, round answers to one decimal place. [A/C 4] a. At which x-coordinates does f have local extrema? Support your answer. [Hint: Think about how you determined the local maximum and minimum points in question #1.] X = b. At which x-coordinates does f have points of inflection? Support your answer. [Hint: Think about how you determined the points of inflection in question #1.] X =
