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 2 outputs.

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 2 outputs.

• No it's not a function because the y value 5 has 2 inputs.
