Answer 1

The correct response is:

It passes the Vertical Line Test.

A graph represents a function if, for every input (x-value), there is exactly one output (y-value). The Vertical Line Test checks this by determining if any vertical line intersects the graph at more than one point. If it does, the graph does not represent a function.
