​

​Learning Targets

​1. define a relation and a function;

​

​2. differentiate a relation and a function through real-life examples/experiences; and

​

​3. find the domain and range of a function

​Relation

​-a set of ordered pairs

​Function

- a relation where there is only one value of y for each value of x.

​Domain

-the set of first values (x) in the ordered pairs

Range

-the set of second values (y) in the ordered pairs

Multiple Choice
