Answer: B. {-2, -1, 0, 1, 2}
The range of a relation is the collective term for the set of the second elements from the ordered pairs, otherwise called the dependent variables (that is, the y - coordinates). Therefore, the domain of this relation will be {-2, -1, 0, 1, 2}
On the other hand, the domain of a relation is the collective term for the set of the first elements from the ordered pairs, otherwise called the independent variables (that is, the x - coordinates). Therefore, the domain of this relation will be {0, 1, 4}
