It looks like a set of coordinates that would all lie along the same straight line, y = x + 9. I would call that a function; however one could fit any number of points with a polynomial function of high enough order.
This is not a very good question for teaching about functions and practical mathematics.
Determine whether or not the relation is a function.
{(-3, 6), (-2, 7), (-1, 8), (0, 9)}

or
no
