Explain how the vertical line test proves that a relation is not a function.
Choose the correct answer below.
O A. A vertical line at a specific x-value of the domain will intersect the graph of a relation at each y-value in the range that
the x-value is mapped to by the relation. The vertical line will intersect the graph more than once if the graph of the
relation is not a straight line. If the graph is a straight line, then the relation is a function; otherwise, it is not a function.
B. A vertical line at a specific x-value of the domain will intersect the graph of a relation at each y-value in the range that
the x-value is mapped to by the relation. If even one such line has more than one intersection, then one input has two
or more outputs and the relation is not a function.
O c. A vertical line at a specific y-value of the range will intersect the graph of a relation at each x-value in the domain that
the relation maps to that y-value. If even one such line has more than one intersection, then one output has two or
more inputs that map to it and the relation is not a function.
D. A vertical line at a specific y-value of the range will intersect the graph of a relation at each x-value in the domain that
the relation maps to that y-value. The vertical line will intersect the graph more than once if the graph is not a straight
line. If the graph is a straight line, then the relation is a function; otherwise, it is not a function.
