-{(6,7), (6,2), (-4,3), (9,5), (-1,8)}
A)domain = {9, -4, -1, 6, -4}; range = {5, 8, 2, 3, 7}
B)domain = {9, 14, -1, 6, -4}; range = {5, 8, 2, 3, 7}
C)domain = {5, 8, 2, 3, 7}; range = {9, 9, -1, 6, -4}
D)domain = {9, -1, 6, -4}; range = {5, 8, 2, 3, 7}

The domain is the set of all x-coordinates, which in this case are {6, -4, 9, -1}. The range is the set of all y-coordinates, which in this case are {7, 2, 3, 5, 8}. Option D is the only one with the correct domain and range. The domain is the set of all x-coordinates, which are 9, -1, 6, and -4. 
The range is the set of all y-coordinates, which are 5, 8, 2, 3, and 7. 
Option D includes the correct values for both the domain and range.
