10-5 Compressions and Stretches of Functions – We learned to identify the effect on the graph of a function of multiplying the output by -1. Next we identified the effect on the graph of a function of replacing f(x) by k f(x) or f (k x) for specific values of k. We discovered that the graphs of functions are transformed when the input and output are multiplied by varying factors of k. Multiplying the output by a factor of k stretches or compresses the graph vertically. Multiplying the input by a factor of k stretches or compresses the graph horizontally.
