五次函数及其性质的研究

摘要

The third and forth power function and the curve character were researched, the extreme point and inflexion were determined by using the existence condition of the fifth function, and the inflection point and the extreme value formula were given.%本文通过对三次函数和四次函数及其曲线性质的研究,利用各次幂的系数来确定五次函数的极值点以及拐点的存的条件,并给出了求拐点和极值的计算公式.
