In this lesson on Relations and Functions, students learn the terminology and concepts of ordered pairs, relations, functions, domains, ranges, and populations. They are shown how to determine if a relation is a function by using the definition that every value in the domain must correspond to only one value of the range. Additionally, they are introduced to the concepts of independent and dependent variables and how to identify them in a given scenario. The lesson ends with an exercise where students graph information and determine if it represents a function.
