Answer 3

Any set of points represent a functin if and only if for every x-value there is but one y-value associated with it.

Answer 4

what does that mean

Answer 5

For example, watch option D:
\[D=\left\{ (-5,3),(-2,0),(-1,2),(6,4),(6,3) \right\}\]
This is NOT a function, because the set of points representative of this plane have two points that share the same x-value but not the same y-value, these being: (6,4) and (6,3)
