The answer to this is the last option choice.
An easy way to solve this is to look at the x in each set. If two or more of the ordered pairs have the same number in the x place, then it is not a function.
The first option isn't a function becasue there are 2 "-7"
The second option isn't a function because there are 2 "1"
The third option isn't a function because there are 2 "-2"
That leaves the bottom choice the answer because none of the x's repeat.
-1/27
