Determine the intervals on which f is increasing or decreasing, assuming the figure below is the graph of the derivative of f. On Interval 1: f is ? V On Interval 2: f is ? V On Interval 3: f is ? V 2 Note: You can earn partial n. Increasing Preview My Answers Decreasing You have attempted this problem U times(1 point) Let at) : 9:3 4.11:2 + 7x 6. Find the open intervals on which f is concave up (down). Then determine the m-coordinates of all inflection points off. 1. f is concave up on the intervals 2. f is concave down on the intervals 3. The inection points occur at :1: = Notes: In the rst two, your answer should either be a single interval, such as (0,1), a comma separated list of intervals, such as (-inf, 2), (3,4), or the word "none". In the last one, your answer should be a comma separated list of a: values or the word "none". (1 point) Let f(ac) = -ac - 823 + 2x - 3. Find the open intervals on which f is concave up (down). Then determine the -coordinates of all inflection points of f. 1. f is concave up on the intervals 2. f is concave down on the intervals 3. The inflection points occur at x = Notes: In the first two, your answer should either be a single interval, such as (0,1), a comma separated list of intervals, such as (-inf, 2), (3,4), or the word "none".
