Please help me find the domain for the following functions. If I understand this correctly I can use any number as long as the denominator does not equal zero
1) y = 7/(1 +x) can be any number except 1
2) y = 2/(6 x) can be any number except 6
3) y = 8/(2x  1)can be any number except 0

(6 x) is zero when x = +6
(2x1) is zero when x = 1/2
