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 -8 -6 -4 -2 2 4 6 8 x y A coordinate system has a horizontal x-axis labeled from negative 5 to 5 in increments of 1 and a vertical y-axis labeled from negative 8 to 8 in increments of 1. The graph consists of two horizontal rays and two line segments that rise from left to right. A horizontal ray extends to the left from the point (0, negative 1). A line segment extends from the point (0, negative 1) to the point (2, 0). A second line segment extends from the point (2, 0) to the point (4, 2). A horizontal ray extends to the right from the point (4, 2). Question content area bottom Part 1 (a) Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
