To determine whether or not a set of points is a function, you must make sure every x-value only has one y-value.

A function is a relationship where an input has exactly one output.

To determine whether or not a graph is a function, we do the vertical line test.

Imagine a vertical line being drawn in the graph. If the vertical line touches the graph at only one point, then it is referred as function. If the vertical line touches more than one point, then it is not a function.
