Answer 1

The Domain of a Relation

Answer:

`\{ -2, 4, 5, 9 \}`

Explanation:

The Domain of a Relation is just the set of the
`x` values of the ordered pairs in the relation (Recall that if you have an ordered pair,
`(a,b)`,
`a` is the
`x` value).

We are given the relation:
`\{(9,-2),(-2,-10),(5,-9),(4,5) \}`. The Domain of this relation is
`\{ 9, -2, 5, 4 \}`.
