Find the domain, and the range when the relation is a list of pairs.
1.f(x) = 2x − 4 + 8Find the domain.
2.f(x) = 9x − 1 + 3Find the domain.
3.f(x) = 3x − 3 − 4Find the domain.
4.f(x) = −1x − 5 + 5Find the domain.
5.f(x) = −5x − 3 − 3Find the domain.
6.f(x) = 6x − 2 − 1Find the domain.
7.f(x) = 6x − 5 Find the domain.
8.f(x) = −5x − 3 − 4Find the domain.
9.f(x) = −7x − 5 − 3Find the domain.
10.f(x) = −2x − 3 + 1Find the domain.
11.f(x) = 9x − 3 − 6Find the domain.
12.f(x) = −3x − 3 + 9Find the domain.
