The given relation does not represent a function because the first coordinate $3$ is paired with two different second coordinates.
Work Step by Step
RECALL:
A function is a relation whose every first coordinate (x) is paired with only one second coordinate (y).
Note that in the given relation, the first coordinate $3$ is paired with two different second coordinates ($6$ and $8$).
Thus, the given relation does not represent a function.
