horizontal stretch graph
Horizontal Stretches and Compressions. A horizontal stretching is the stretching of the graph away from the y-axis. A horizontal compression is the squeezing of the graph towards the y-axis. A compression is a stretch by a factor less than 1. If | b | < 1 (a fraction between 0 and 1), then the graph is stretched horizontally by a factor of b units. If | b | > 1, then the graph is compressed horizontally by a factor of b units.
