1. 4.4 – relations, domain, & range
Textbook
pg. 268
Objective:
The student will identify domain and range in a function in order interpret graphs.

2. relation: any set of data with an input (x-values) and an output (y-values) mapping diagram: similar to a table, but with arrows
The following ordered pairs represents track scoring places and the points given to each. Represent them in a table, graph, and mapping diagram.
(1, 5) (2, 3) (3, 2) (4, 1)

3. Domain: input (all x-values) Range: output (all y-values)
2) Go back to #1 and state the domain and range
