Question

Identify the domain and range of the relation.
(-4, 2), (-9,-5), (-4, 12), (8,-8)

Answer 1

Domain: -4, -9, -4, 8

Range: 2, -5, 12, -8

Explanation:

Domain represents the independent variables, or the x coordinates

Range represents the dependent variables, or the y coordinates

The x coordinates or domain in this relation are:

-4, -9, -4, 8

The y coordinates or range in this relation are:

2, -5, 12, -8

Answer 2

The domain of the relation is the set of all the first components of the ordered pairs, which in this case is the set {-4, -9, -4, 8}. The range of the relation is the set of all the second components of the ordered pairs, which in this case is the set {2, -5, 12, -8}.

Therefore, the domain of the relation is {-4, -9, -4, 8} and the range of the relation is {2, -5, 12, -8}.
