Question

Can someone help me get the correct answer

Answer 1

I think it's the answer C, because in the second and third pairs, the -2 are the same.

Answer 2

A. Yes, because every x-value corresponds to exactly one y-value. always look at the x value (x,y) make sure its not repeated.

(-4,-1), (-3,-3), (-1,-5), (-4,-7) < this would not represent a function because there are 2 (-4) in the x value.
