Given f(x)= |x-1|/x^2-25 please determine the domain. Thank you!

A. All real numbers except -5 and 5
B. All real numbers except -5,0 and 5
C. All real numbers except 0
D. All real numbers except 0 and 5

    the only thing you have to worry about in your function is division by zero

    When does that happen?
    When x^2 - 25 = 0
    or when x^2 = 25
    or when x = ± 5

    so your domain is any real number, except x = ±5
    which would be a)
