Answer:
OPTION 2
Step-by-step explanation:
The vertical line test can be used to determine whether a graph represents a function. A vertical line includes all points with a particular x value. The y value of a point where a vertical line intersects a graph represents an output for that input x value. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output. A function has only one output value for each input value.

HOW TO: GIVEN A GRAPH, USE THE VERTICAL LINE TEST TO DETERMINE IF THE GRAPH REPRESENTS A FUNCTION.
1.Inspect the graph to see if any vertical line drawn would intersect the curve more than once.
2.If there is any such line, the graph does not represent a function.
3.If no vertical line can intersect the curve more than once, the graph does represent a function.
(The 2nd pic represents a graph that has a function)
