Answer:
Not a function.
Step-by-step explanation:
The definition of a function specifies that no value of <em>x</em> can be paired with two or more different values of <em>y</em>.
In the given relation: {(6, 2), (8, 2), (6, 3), (12, 3)},
The input value of x = 6 has two corresponding output values (y-coordinates): 2 and 3.
Therefore, the given relation is not a function.
