Use the graph to determine a. open intervals on which the function is increasing, if any. b. open intervals on which the function is decreasing, if any. c. open intervals on which the function is constant, if any. -5 -4 -3 -2 -1 1 2 3 4 5 6 7 -5 -4 -3 -2 -1 1 2 x y A coordinate system has a horizontal x-axis labeled from negative 5 to 7 in increments of 1 and a vertical y-axis labeled from negative 5 to 2 in increments of 1. A line that falls from left to right starts at the plotted point (negative 4, 1) and ends at the plotted point (6, negative 4). Question content area bottom Part 1 a.
