Answer:

Yes, it is a function

Explanations:

Note:

A relation/graph represents a function if for every value of the independent variable (x), there is a unique value of the dependent variable (y).

If for a single value of x, there is more than one value of y, then the relation does not represent a function.

In the relation shown on this graph, we would observe that, for every value of x, there is just one value of y. That is, each value of x is mapped to a single value of y. Therefore, the relation represented by the graph shown is a function.
