Answer 1

To determine the domain and range of the given relation, we need to identify the set of all first elements (x-values) and the set of all second elements (y-values) from the ordered pairs.

The given ordered pairs are:
1. (8, -5)
2. (2, 1)
3. (6, 2)
4. (-1, 6)
5. (-10, 1)

**Domain:** This is the set of all first elements (x-values).
- From the pairs: 8, 2, 6, -1, -10
- Therefore, the domain is: {8, 2, 6, -1, -10}

**Range:** This is the set of all second elements (y-values).
- From the pairs: -5, 1, 2, 6
- Therefore, the range is: {-5, 1, 2, 6}

In summary:
- **Domain:** {8, 2, 6, -1, -10}
- **Range:** {-5, 1, 2, 6}
