2) A 270-degree counterclockwise rotation about the origin followed by a translation 2 units to the right
3) A translation 2 units down followed by a 90-degree counterclockwise rotation about the origin
4) A translation 2 units down followed by a 270-degree counterclockwise rotation about the origin
