Question

What is the domain and the range of the relation represented by the ordered pairs?

{(2,3),(−2,4),(1,6),(0,4)}

Select each correct answer.

domain: {−2,0,1,2}
range: {3,4,6}
range: {−2,0,1,2}
domain: {3,4,6}

Answer 1

domain: {−2,0,1,2}

range: {3,4,6}

Explanation:

The domain of any relation is the set of x-values. In this case, the x-values are 2, -2, 1 and 0; from least to greatest, this is {-2, 0, 1, 2}.

The range of any relation is the set of y-values. In this case, the y-values are 3, 4, 6 and 4; we do not need to write any values that repeat, so from least to greatest, this is {3, 4, 6}.

Answer 2

Domain: (-2, 0, 1, 2)
Range: (3, 4, 6)
