Answer is u know please

Explanation:

We're looking for a point where the x coordinate isn't already taken or used up.

In the original set of points, we have the x values -3, 8, 0, and -5 taken. We cannot use them for other points. This is because any x value must go to exactly one y value.

So for instance, if we pick (-5,10) to put into the set, then x = -5 would repeat itself. We would have x = -5 map to y = -14 and y = 10 at the same time. But this means we don't have a function. So we can rule out choice A.

Choices C and D are ruled out for similar reasoning.

Only choice B has an x coordinate where x = 1 wasn't used earlier.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
