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

Is the relation a function? Why.

No, because the x-value 11 has two y-values pair with it.

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

Does the graph represent a function?

No, because the vertical line test shows there are repeating input values

Yes, because the vertical line test shows there are no repeating input values

Does this mapping diagram represent a function?

Yes, for each input there is only one output

No, multiple inputs result in the same output

What is the domain of the mapping?

{ (-4, 3), (1, 8), (3, 2), (7, 3) }

What is the range of the mapping?

{ (-4, 3), (1, 8), (3, 2), (7, 3) }
