    I know this is basically saying y(x) =

    So say we take a coordinate used for the table of values from II if y(x) does that mean if we plug in 1 for y and then solve the problem should we get the same coordinate ? I am confused how to represent this

    It's asking you which of the three are functions. You don't actually have to plug anything in.

    Functions will pass the vertical line test when they're graphed and never have the same input listed twice when given a list of points. So that's how you'd evaluate them

    so with that being said then, so 3 would be alright then? Since no inputs are repeating?

    Yes just saw that as well so then to test I you would just fill in your own table of values and test and then graph to test?

    actually. Since its a quadratic function it would be alright as well then?
