What do you call the line test used to determine if a graph represents a function?

• Horizontal line test

• Vertical line test

• Curved line test

• Straight line test

Using the vertical line test, does the given graph represents a function?

• Yes, because the line crosses the graph at exactly one point.

• No, because the line crosses the graph at two points.

• Yes, because the line does not cross the graph at any point.

• No, because the line crosses the graph at four points.
