      Math again? Google isn't helpful

      Amiright?

      Find the intervals on the real number lin for which the radicand is nonnegative(greater than or equal to zero).

      1. Sqrt(x-5)

      2. (7-2x)^(1/4)

      I don't understand the question...but my answers are this.
      1. X>5

      2. X<3.5 or X<7/2
