The graph represents a piecewise linear function. The function passes through the origin (0,0). For x < 0, the function is a line segment with a negative slope. For x > 0, the function consists of two line segments with positive and then negative slopes. The points on the graph appear to be approximately: (-2, -2), (-1, -1), (0, 0), (1, 1), (2, 1.5), (3, 1).
