Give the domain and range of the relation.
-{(-4, -5), (9, -1), (7, 3), (-3, -3)}
A)domain = {9, -3, -4, 7}; range = {-1, -3, -5, 3}
B)domain = {-1, -3, -5, 3}; range = {9, -3, -4, 7}
C)domain = {9, -3, -4, 7}; range = {-1, 5, -3, -5, 3}
D)domain = {9, -3, -4, 7}; range = {-1, -1, -3, -5, 3}

To find the domain, we list out all the x-coordinates of the ordered pairs: {-4, 9, 7, -3}. This gives us the domain of {9, -3, -4, 7}. To find the range, we list out all the y-coordinates of the ordered pairs: {-5, -1, 3, -3}. This gives us the range of {-1, -3, -5, 3}. So, the correct choice is A.
