Graph in two parts. Part one is increasing from -infinity in quadrant 3 to pass through (-3, -2) and (-1, 2) and continues increasing upward in quadrant 2. Part 2 is increasing from -infinity in quadrant 4 and passes through (1, -2) and (3, 2), then continues increasing upward to the right in quadrant one.
