The graph of the piecewise function includes 
(1) a straight line passing through point (-3, 0) and stopping at point (0, 3) with an unshaded small circle at the end of point (0, 3) and an arrow at the other end.
 (2) a shaded small circle at point (0, 5), and 
(3) a straight line starting at the point (0, -1) and passing through the point (2, 3) with an unshaded small circle at the point (0, -1) and an arrow at the other end.
