Answer:

Top-left box(Option 1 I guess)

Explanation:

We know that a graph of points is a function if there is never two or more points that lie on the same vertical line.

Using this to test the graph, we see that the top-left option has no vertical line that passes through 2 or more points. So, it is a function.
