The graph of a curve that passes the vertical line test is known as a function. Functions are graphical representations that may have multiple x-values for a given y-coordinate, but will never have multiple y-values for any given x-coordinate. Hope that helped! =)
It is called function. to use the vertical line test<span>, take a ruler or other straight edge and draw a </span>line<span> parallel to the y-axis for any chosen value of x. If the </span>vertical line<span> you drew intersects </span>the graph<span> more than once for any value of x then </span>the graph<span> is not </span>the graph<span> of a function.</span>
