二次函数作为高中数学中一个重要的知识点,历年来的高考数学卷中都有涉及二次函数及其应用的题型,其难点往往涉及零点问题的讨论。下面列举几例,对与二次函数零点相关的题型进行探究。题型一根据对称性质探求零点之和
As an important knowledge point in high school mathematics, the quadratic function has many kinds of questions involving the quadratic function and its application in the math test in the past years. The difficulties often involve the discussion of the zero point. Here are a few examples to explore the questions associated with the zero point of the quadratic function. A type based on symmetry to explore the sum of zeros
