Using Graphs to Relate Two Quantities Objective: To represent mathematical relationships using graphs Essential Understandings:Graphs can be used to visually represent the relationship between two variable quantities as they change. Tables and Graphs can both show relationships between
variables.

Graphing a Function Rule Objective: To graph equations that represent functions Essential Understandings:The set of all solutions of an equation form its graph A graph may include solutions that do not appear in a table A real world graph should show only points that make
sense in the given situation.

Formalizing Relations and Functions Objective: To determine whether a relation is a function. To find domain and range and use function notation Essential Understandings:A function is a special type of relation where each value in the domain is paired with one value in the range. The vertical line test shows whether a function is a
relation.
