I hope this is helpful xD :)

Answer 2

Every input (x value) must have a unique output (y value) for a relation to be considered a function.The vertical line test can be used to determine if a relation is a function. From the choices the point that should be eliminated is (-4,5) because vertical line will pass with (-4,3).
