Answer:
B, C
Step-by-step explanation:
I am sure you have heard of the vertical line test. What the vertical line test does is make sure, for every, input, there is only one output. What this means is that two points cannot have the same x, unless they have the same y.
Two different x's can have the same y, but two different y's cannot have the same x.
In this problem, the x's that are taken by other coordinates with different y values are: 1, 3, 4, -4.
This means that the x you are trying to find cannot be any of those since the y value is different than all the other points. Which leaves you with the answers B and C.
Hope this helps, don't hesitate to ask more questions.
