Final answer:
No, the given relation is not a function as there are repeated x-values.
Step-by-step explanation:
A relation is a function if each input value (x-value) corresponds to exactly one output value (y-value). To determine if the given relation is a function, we need to check if there are any repeated x-values.
In the given relation (8,2)(-4,1)(-6,2)(8,9), we can see that the input value 8 has two different output values, 2 and 9. Therefore, this relation is not a function.
