Does the graph represent a function?

Answer:
Yes, the graph represent a function.
Step-by-step explanation:
We have been given a graph. We are asked to determine whether the graph represent a function or not.
To check a graph is function or not, we use vertical line test. We draw a vertical line on graph and see if it crosses the graph more than once, then the graph is not function.
If vertical line crosses a graph only once, then the graph is a function.
Since our given graph is a horizontal line, so each vertical line will intersect the graph exactly at one place, therefore, the graph is a function.
