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

{1, 3, 5, 7, 9}

Answer 1

The domain of a function refers to the set of all possible input values. In this case, the input values are the x-coordinates of the given points. Looking at the x-coordinates of the points in the function {(3, 6), (5, 7), (7, 7), (8, 9)}, we can see that the possible input values are 3, 5, 7, and 8. Therefore, the correct answer is {3, 5, 7, 8}.
