What values can you and can you not input into a function? What values can the function output? The domain is the set of values that the function is defined for (i.e., the values that you can input into a function). The range is the set of values that the function output can take on.
This tutorial covers the ideas of domain and range through multiple worked examples. These are really important ideas as you study higher mathematics.
