The image shows that the curve is a graph of a function. This obviously means that the relation showed in the graph is a function.
VERTICAL LINE TEST
It is a method used in the problem to know whether the given relation is a function or not. All you need to do is to draw a vertical line through the points in the graph, and then observe the points of intersections.
If a vertical line exactly intersects the graph of a relation at one point, it indicates that the value of x is exclusively paired with one unique value of y, implying that the relation is a function. On the other hand, if the vertical line intersects the graph more than once, it indicates that more than one value of y is paired to the value of x, implying that the relation is no longer a function.
