Question

PLEASE HURRY

Which statement best illustrates using the vertical line test to determine if the graph below is a function of x?
On a coordinate plane, a circle is centered around (0, 0).

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

Explanation:

A

a vertical line is parallel the y-axis (up and down). if this line now intersects the grain at 2 points, it means that the x value of that line has 2 different result values as y.

but as function it can have only one result value per x value.
