Staff Review
This lesson does a great job of showing you how to identify the input and output of a real-world relationship. Other vocabulary terms such as independent / dependent variables, and domain / range are discussed. This lesson serves as an excellent introduction to some basic terminology of functions. Several examples are shown and discussed in this video, and the problem set is very helpful as well.
