Question

What are the domain and range of the relation {(–5, 5), (–3, 2), (0, 3), (3, 2)}?









A.

Domain: {0, 2, 3, 5}; Range: {–5, –3}








B.

Domain: {2, 3, 5}; Range: {–5, –3, 0, 3}








C.

Domain: {–5, –3, 0, 3}; Range {–5, –3, 0, 2, 3, 5}








D.

Domain: {–5, –3, 0, 3}; Range {2, 3, 5}

Answer 1

the domain is the set of x-values (the x-values is the first number in each parenthesis)
The range is the set of y-values

Answer 2

Note repeated numbers are only included once.

Answer 3

So for example if the x values were 1,2,2 and 3 the domain would be {1,2,3}
