Work Step by Step
The multiplication of the function results in vertically stretching or shrinking. Using $c=1$ as a reference.,$c=2$ is a vertical stretch by a factor of 2, $c=5$ is a vertical stretch by a factor of 5, and $c=1/2$ is a vertical shrink by a factor of 1/2. Hence, the larger $|c|$ is, the more narrow and tall the graph becomes.
