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.

Is this table a function and how can you tell?

• Yes its a function because there are not variables for missing numbers
• No it's not a function because the y value 4 repeated
• No it isn't a function because the x value 2 is repeated
• No it's not a function because the x value 5 has y values of  10 & 12
