Is the relation shown a function ?

No, because the x -value 11 is paired with 5 and 8.

Yes, because each x -value has only one y-value paired with it.

Is this mapping a function and how can you tell?

No it's not a function because the x value 5 has 2 outputs.

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 y value 5 has 2 inputs.

Is this table a function and how can you tell?

No it's not a function because the x value 5 has 2 outputs.

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
