To find the domain of the relation, we look at the sets of values given. The domain is the set of all possible inputs (or \(x\)-values) for the relation.
In the provided sets, we have the following values for \(x\):
- The first set of \(x\)-values: \(-4, 0, 1, 2\)
- The second set of \(x\)-values: \(-7, -6, 2, 3, 11\)
Now, we'll take the union of these two sets to find the complete domain:
- From the first set: \(-4, 0, 1, 2\)
- From the second set: \(-7, -6, 2, 3, 11\)
Combining these, we have:
\(-7, -6, -4, 0, 1, 2, 3, 11\)
Note that the number \(2\) appears in both sets, but we only list it once in the domain.
Thus, the domain of the relation is:
\[ { -7, -6, -4, 0, 1, 2, 3, 11 } \]
