Yes, the graph represents a function.

Here’s why:
A graph represents a function if every value of $x$ has exactly one corresponding value of $y$. This means that the graph should pass the vertical line test—if you draw a vertical line anywhere on the graph, it should intersect the graph at most once. In this case, the line shown in the graph passes this test, so it is a function.

Tip:

When checking if a graph represents a function, always test with a vertical line. If any vertical line intersects the graph at more than one point, it is not a function.
