1.2.3 Exploring Transformations (continued) Example 3 Stretching and Compressing Functions Horizontal and vertical stretches and compressions are tranformations where the points on a figure are either pulled away from or pushed towards the x - or y -axis. • In a horizontal stretch, each point is pulled away from the y -axis and each x -coordinate changes. • In a vertical stretch, each point is pulled away from the x -axis and each y -coordinate changes. • In a horizontal compression, each point is pushed towards the y -axis and each x -coordinate changes. • In a vertical compression, each point is pushed towards the x -axis and each y -coordinate changes.
