Section 4 – 3

Relations

Using the example on page 205 provide a

Table and Mapping for the following Order Pairs:

(1, 2) (3, -4) (5, 6) (7, -8)(7, 8)

(1, 2) (3, -4) (5, 6) (7, -8) (7, 8)

TableMapping

x yx y

What are the Domains and Range of the relation?

(1, 2) (3, -4) (5, 6) (7, -8)(7, 8)

Domain:

Range:

Now graph the relation on the coordinate plane (be sure your Plane is at least From -10 to +10 on both axis):

(1, 2) (3, -4)

(5, 6) (7, -8)

(7, 8)

What is the INVERSE of the relation:

Original:(1, 2) (3, -4) (5, 6) (7, -8)

(7, 8)

Inverse:( , ) ( , ) ( , ) ( , ) (

, )

Now on the sameplane, graph the Inverse of therelation

(1, 2) (3, -4)

(5, 6) (7, -8)

(7, 8)

(2, 1) (-4, 3)

(6, 5) (-8, 7)

(8,7)
