    5root(x) has no limitations since it is an odd radical.

    An odd degree root allows you to have anything under the radical.

    thanks! What exactly does that mean I do next? Excuse my lack of understanding with this, but I missed class for this section. So it could be helpful if someone could help walk me through it! :)

    3root(-8) = -2 4root(-16) is undefined..

    if your looking for interval notation: Domain: (-inf,inf)

    other notation would be: Domain: {x|x is an element of R}

    ohh ok. So that would be the answer to this problem? I never know what exactly needs to be done with the numbers, but I noticed this was a common answer for some

    actually, this is an online assignment and I just realized that I had put that answer and it told me that was the wrong format.. So they must be looking for another kind of answer. (it says to round any decimal values to two decimals.. so it could possibly be a number answer

    maybe it's because I didn't do the parenthesis
