no

Explanation:

Step1: Recall Vertical Line Test

A graph represents a function if every vertical line intersects the graph at most once.

Step2: Apply Vertical Line Test

For the given graph, if we draw any vertical line, it will intersect the graph at only one point. So, it passes the vertical line test.

Answer:

Yes
