{(6, 3), (7, 5), (7, 7), (9, 8)}
{(6, 3), (7, 5), (7, 7), (9, 8)}

{1, 3, 5, 7, 9}
{1, 3, 5, 7, 9}

The domain of a function refers to the set of all possible input values or x-values. In this case, the domain consists of the x-values in the given function, which are 3, 5, 7, and 8.

Therefore, the correct response is: {3, 5, 7, 8}.
