    Those are the only 2 that only have a positive range...

    No, square root is not one of the answers.

    For example, the square root of 9 could be negative 3.

    when we graph y = sqrt(x) we only consider non-negative y values

    square root is one of them.

    ^ right, this is actually a bit confusing at first when we take the square root of a number, we consider the positive and negative square roots but as a function, sqrt(x) only gives positive values
