1. (1 point) Determine the intervals on which f is increasing or decreas ing, assuming the figure below is the graph of the derivative of f. 19 419 1.0 On Interval 1: f is ? On Interval 2: f is ? On Interval 3: f is ? 2. (1 point) If the figure below is the graph of the derivative f , answer the following: Where do the points of inflection of f occur? On which interval(s) is f concave down?3. (1 point) Use the given graph of the function f to answer the following questions. If a question has two or more answers separate them with commas. 1. List the open interval(s) on which f is concave upward. For credit your interval(s) must be as large as possible. Answer (in interval notatiom: 2. List the open interval(s) on which f is concave down- lard. For credit your interval(s) must be as large as possible. Answer (in interval notatiom: 3. List the points of inection.
