How to find the correct domain in a composite function?

  1. Feb 8, 2017 #1
    1. The problem statement, all variables and given/known data
    The problem states f(x)= √x-5). When solving for (f)/(f)(x) I got the answer=√(√x-5)
    I cannot get the interval notation correct as many times as I input the domain. The square root must of a square root has confused me.

    2. Relevant equations

    3. The attempt at a solution
    (-∝,-√5]∪(0,√5]
