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

  • algebra -

    (6- x) is zero when x = +6

    (2x-1) is zero when x = 1/2
