In the given relation, observe that in the first and last ordered pair, the x-coordinate has two different y-coordinates. The x-value 4 has two different y-values as 5 and 7.
Since each element of the domain does not have a unique value in the range, so the relation is not a function.
Thus, the given relation is not a function.
