Answer:
No, because it fails the vertical line test
Explanation:
The vertical line test can easily be used to determine if a graph represents a function or not. It is also very simple.
At any point in the graph, draw a vertical line. If the line intersects the graph more than once, the graph is NOT a function.
In your case, this graph fails the vertical line test, so it is not a function.
