Question

which statement best illustrates using the vertical line test to determine if the graph below is a function of x ?

A) the graph is not a function of x because the line x = 0 intersects the graph at two points.

B) the graph is a function of x because the line x = 5 does not intersect the graph

C) the graph is not a function of x because the line y = 0 intersects the graph at two points

D) The graph is a function of x because the line y = 5 does not intersect the graph

Answer 1

If something is a function, every x-value, only has one (1) y-value. If the line x = 0 intersects the graph in two points, there are to values for y (instead of one). Therefore the graph is not a function of x.

Your answer is A.
