1.1 Function Families
Here you will learn to identify primary function families by their equations and graphs. This will set the stage for
analyzing all types of functions.
Functions come in all different shapes. A few are very closely related and others are very different, but often
confused. For example, what is the difference betweenx^2 and 2x? They both have anxand a 2 and they both equal
4 whenx=2, but one eventually becomes much bigger than the other.
