Question: Find the domain and range of the relation graphed.



A ) domain = {3, 0, 4, 2}; range = {0, 1, 2, - 2, - 3}
B ) domain = {0, 1, 2, - 2, - 3}; range = {3, 0, 4, 2}
C ) domain = {2, 4}; range = {- 3, 2}
D ) domain = {1,- 2}; range = {3}

Steps to derive

1 The ordered pairs from the given graph are {(0, 3), (1, 0), (2, 4), (- 2, 0), (- 3, 2)}

2 The domain of a relation is the set of all the first coordinates of the ordered pairs. The range of a relation is the set of all the second coordinates of the ordered pairs.

3 The domain is {0, 1, 2, - 2, - 3}.

4 The range is {3, 0, 4, 2}.



Hence the right answer is Option B
