Question

Part II: Identify the domain and range of the following relations. Then determine if the relation is a function or not. ** 7) 8) 9) X Function? Domain: Function? Domain: Function? Domain: Range: Range: Range:

Answer 1

Part 7

The domain is the interval [-4,4]

The range is the interval [0,4]

Represent a function

Part 8

In the interval (-3,-1]

domain is the interval (-3,1]

range is the number 2

In the interval [-1,1]

domain is the interval [-1,1]

range is the interval [-2,2]

in the interval [1, infinite)

domain is [1, infinite)

range is the number 2

Represent a function

Part 9

The domain is all real numbers

The range is the interval (-infinite, 3]

Represent a function
