Answer the question.Explain why the vertical line test works when determining whether a graph is the graph of a function.
What will be an ideal response?
A function can have no more than one y-value for any given x-value. A vertical line is the graph of the equation x = a. Therefore, if a vertical line does not intersect the graph more than once, it means that there is not more than one y-value for that value of a.
