The domain of the relation consists of all the first elements from each ordered pair. In this case, the first elements are -7, 7, 6, -5, and -4. Thus, the domain can be expressed in set notation as:

To double-check, just list out the first components from each pair: (-7, 4) gives -7, (7, 0) gives 7, (6, 5) gives 6, (-5, 2) gives -5, and (-4, -5) gives -4. All are accounted for, confirming the domain is correct!
