    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        9.9 * x ^ 3 - 98.31 * x ^ 2 + 216.81 * x - 40.77 ≥0         (1)

---

    From inequality(1)：
         0.207085 ≤ x ≤ 2.925434 或  x ≥ 6.797784

---

    The final solution set is :
         0.207085 ≤ x ≤ 2.925434 或  x ≥ 6.797784
