CCSS.HSF.IF.A.1

Is the relation shown in the mapping a function?

• No, because -1 and 4 are pared with 4.

• Yes, because every input is paired with exactly one output.

CCSS.HSF.IF.B.5

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.
