Compression of a Graph

Shrink
Compression of a Graph

A transformation in which all distances on the coordinate plane are shortened by multiplying either all x-coordinates (horizontal compression) or all y-coordinates (vertical compression) of a graph by a common factor less than 1.

Note: When the common factor is greater than 1 the transformation is called a dilation or a stretch.

Two sine waves: "Original graph" with full amplitude, and "Same graph, vertically compressed" with reduced amplitude.
