1. Section 4.2

2.  Label the quadrants on the graphic organizer  Identify the x-coordinate in the point (-5, -7)

3.  Ordered Pairs Table Graph

4.  A __________________ is any set of ordered pairs  Relations can be represented as a _____________ and as a _____________  The _________________ of the relation is the set of x-coordinates  The _________________ of the relation is the set of y-coordinates

5.  Domain  The x-values of a function  Input, independent variable  Look at the graph horizontally  Range  The y-values of a function  Output, dependent variable  Look at the graph vertically

6. State the domain and range of the following: {(1,-2), (0,-1), (3,1)}.  State the domain and range.

7.  Express the relation as table and a graph. Then state the domain and range.  1. (-4,3)(2,1)(0,3)(-3,-2)

8.  Express the relation as table and a graph. Then state the domain and range.  1. (5,3)(-4,1)(2,-5)(3,-4)

9.  Express the relation as table and a graph. Then state the domain and range.  1. (8,5)(-6-2)(2,5)(0,-6)

10.  How do tables and graphs represent functions?  ______________________________________ ______________________________________ ______________________________________ ______________________________________
