Since you have not included the graph, we have no way of knowing. However, you can figure out which one by finding one of the ordered pairs of the graph and putting these values into every equation. (Don't stop when you find the first one that works!).

If only one equation works, you have found it; if more than one equation works, take another point, and put its values into the equations that worked for the first point. Keep doing this until you have only one equation that always works.

It will reduce your work if you realize that the first equation creates a straight line; so if the graph is a straight line, that's your answer.

The last equation creates a "V" shape.

The middle two equations are parabolas -- "U" shapes.
