For something to be a function, the input (x value) can ONLY HAVE ONE output (y value), so if x has multiple outputs, it is not a function

B is not a function because x = 2 and x = 9 has 2 outputs

Your answer is AAnswer:Step-by-step explanation:A represents a function.Why? Because all the x-values are unique (no duplications).B does not represent a function. Why? Because the input 4 is repeated and has different y-values for this one input, and similarly the input 9 is repeated.
