Which of the graphs is NOT a function?

• Graph A
• Graph B
• Graph C
• Graph D

Does the graph represent a function?

• Relation
• Linear
• Exponential
• Function

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.

CCSS.8.F.A.1

Is this mapping a function and how can you tell?

• Yes its a function cause all the numbers have lines
• No it's not a function because there a 5 in both ovals
• No it's not a function because the x value 5 has y values of  2 & 9
• No it's not a function because the y value 5 has x values of  2 & 9
