[ 1/1Inequality]
    Assignment:Find the solution set of inequality absx ≥0 ≥-xx .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
         abs x ≥0         (1)
        0 ≥ - x * x         (2)

---

    From inequality(1)：
         x ≤ 0 或  0 ≤ x ≤ 0 或  x ≥ 0
    From inequality(2)：
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

---

    From inequalities (1) and (2)
         x ≤ 0 或  0 ≤ x ≤ 0 或  x ≥ 0    (3)

---

    The final solution set is :
         x ≤ 0 或  0 ≤ x ≤ 0 或  x ≥ 0
