    Domain

    I'm having a lot of trouble with finding the domain of this question:

    sqrt(8x-4)/sqrt(x)

    I get [.5, inf), which I'm told is wrong.

    From the denominator it is clear that x\neq 0 or x \neq \mathbb{R}^-

    In the numerator 8x-4 > 0 giving x > \frac{1}{2}

    Your solution sounds good to me.
