The graph of the relation shown in the table is not provided, but based on the points given, it appears that the relation is a function because each input (x-value) corresponds to only one output (y-value).
A relation is a function if for each input there is only one output. In this case, for each x-value, there is only one y-value. This means that no vertical line will intersect the graph at more than one point, indicating that the relation is a function.
