Answer:
A. No, the graph fails the vertical line test.
Step-by-step explanation:
First let's see what a vertical test is.
It is a test used to find the whether the given graph is a function or not.
We draw a vertical line on the given graph, if the line cuts the graph at only one point of the graph, then it is a function.
If the line cuts the graph at more than one point, then it is not a function.
So, if we draw a vertical line on the given circle, the vertical line cuts the graph at two points of the graph.
Therefore, it is not a function and it is fails the vertical test.
Answer is A. No, the graph fails the vertical line test.
Herewith I have attached the figure.
