Four parabolas, the red and blue ones being upward-facing, and the orange and green ones being downward-facing. The green one passes through (0, -1) and (-2, -3); the orange one passes through (0, -1) and (-1, -3); the red one passes through (0, 1) and (2, 3); the blue one passes through (0, 0) and (1, 2); all of the graphs have a vertex on the y-axis
