[ 1/1Inequality]
    Assignment:Find the solution set of inequality -1 ≤sqrt(x)-(x-3)/2 ≤1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities:
        -1 ≤ sqrt ( x ) - ( x - 3 ) / 2         (1)
         sqrt ( x ) - ( x - 3 ) / 2 ≤1         (2)
        From the definition field of √
         x ≥ 0        (3 )

    From inequality(1):
         x ≤ 11.898979
    From inequality(2):
         x ≥ 5.828427
    From inequality(3):
         x ≥ 0

    From inequalities (1) and (2)
         5.828427 ≤ x ≤ 11.898979    (4)
    From inequalities (3) and (4)
         5.828427 ≤ x ≤ 11.898979    (5)

    The final solution set is :

         5.828427 ≤ x ≤ 11.898979
