Transformations of Functions IV - Horizontal Stretch, Compression, Reflection | Functions | Lulumath

In this video, we will be looking at horizontal stretches, compressions, and reflections (reflections in the y-axis). We will look at what these transformations are, how they affect the graph, and how to apply them.
