Is this graph a function or not a function? 

• Function

• Non Function

• yes

• no

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.

All of the y values or outputs are called what?

• Domain
• Range
• Relation
• Function
