Idont need any work just the answer for both worth 300 points

So because there are 2 x's with 4 and they both have different outputs ( y values are different) it cannot be a function.

The answer is D.

2) There are two x's using -3 and each Y value is different, one is 2 and the other is 0, so it is not a function.

The answer is D.
