Domain and Range Practice

All of the x values or inputs are called what?

• Domain

• Range

• Relation

• Function

All of the y values or outputs are called what?

• Domain
• Range
• Relation
• Function

Give the DOMAIN of the set of ordered pairs: (2, 11), (9, -3), (7, 21), (-8, 6)

• {2, 9, 7, -8}

• {11, -3, 21, 6}

• -8 < x < 9

• -3 < y < 21

Identify the domain of the following relation:

• {-6, 14, 2, 28}
• {(-6,14), (0,32), (2,38), (4,44)}
• {-6, 0, 2, 4}
• {14, 32, 38, 44}

What is the range?

• {-3, -1, 2, 4}
• {0, 4, 7} 
• {0, 4, 4, 7}
• {7, 4, 0}

Which mapping diagram is not a function?

• 
• 
• 
• 

Does this table represent a function?

• Yes!
• No!
• I Don't Know

Is the relation a function? Why?

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.

Identify the domain of the following relation:

• -6, 14, 2, 28
• (-6,14), (0,32), (2,38), (4,44)
• -6, 0, 2, 4
• 14, 32, 38, 44

What is the range of the following graph?

• {-5, -1, 0 , 1, 5}

• {-4, -2, 0, 3, 6}

• (-4, 1) ( 6, 0)

• (6, 0)
