Does this graph show a function? explain how you know.

Option A.

Step-by-step explanation:

Vertical line test : If the graph of a relation intersect any vertical line at most once, then the graph passe the vertical line test and we can say that the graph shows a function other wise it is not a function.

Draw a vertical line, which passes through the point (5,0), i.e.,x=5.

From the graph it is clear that the vertical line x=5 intersect the graph at two points. It means the graph fails the vertical line test.

Since the graph fails the vertical line test, therefore the graph does not show a function.

Hence, the correct option is A.
