Question

10 POINTS AND BRAINLIEST ITS FOR MY SEMESTER TEST PLEASE HELP!!! SEE PICTURE

Answer 1

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.
