    Assignment:Find the solution set of inequality 99-63x^3大于等于79x^4 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        99 - 63 * x ^ 3 ≥79 * x ^ 4         (1)

---

    From inequality(1)：
         -1.33006 ≤ x ≤ 0.903222

---

    The final solution set is :
         -1.33006 ≤ x ≤ 0.903222
