三次函数(fx)=ax~3+bx~2+cx+d(x≠0)是高中数学中一个重要的知识点,在高考和一些重大考试中频繁出现有关它的单独命题,有时甚至以压轴题的形式出现,这应该引起我们的重视。下面我们列举近几年的高考题来研究三次曲线的一些题型。
The third-order function (fx) = ax ~ 3 + bx ~ 2 + cx + d (x ≠ 0) is an important knowledge point in high school mathematics. Frequently, Finale questions appear in the form, which should arouse our attention. Below we list the college entrance examination in recent years to study some of the three types of questions.
