Question

Objective A Find the domain and the range of each relation. See Example 1. 1. {(2,4),(0,0),(−7,10),(10,−7)} 2. {(3,−6),(1,4),(−2,−2)} 3. {(0,−2),(1,−2),(5,−2)} 4. {(5,0),(5,−3),(5,4),(5,3)}

Answer 1

The domain and range of each relation can be determined by listing the x-values and y-values from the given ordered pairs. The domain represents the input values, while the range represents the output values.

Step-by-step explanation:

The domain of a relation refers to the set of all possible input or x-values of the relation, while the range refers to the set of all possible output or y-values. To find the domain of a relation, we list all the x-values from each ordered pair. In this case, the domain for each relation is:

1. {2, 0, -7, 10}
2. {3, 1, -2}
3. {0, 1, 5}
4. {5}

The range of a relation refers to the set of all possible output or y-values of the relation. To find the range, we list all the y-values from each ordered pair. In this case, the range for each relation is:

1. {4, 0, 10, -7}
2. {-6, 4, -2}
3. {-2}
4. {0, -3, 4, 3}
