    ive been asked...

    A real-valued function of a real variable is defined by

    f(x) = 1/(√(|x|-(1/x))) (sorry its abit hard to read it properly)

    Assuming the maximal domain convention, what is the domain of f?

    how would i do this?

    From here

    If a function is given by a formula and the domain is not stated explicitly, the convention is that the domain is the set of all numbers for which the formula makes sense and defines a real number.

    So essentially, work out the domain assuming that there are no restrictions on x other than the natural restrictions imposed by the function itself.
