如何求解二次函数在区间上的最值,是一个综合性较强的问题,影响二次函数在某区间上最值的是区间和对称轴的位置.本文就区间和对称轴动与静的变化进行分类,探索求最值的方法.
How to solve the maximum value of the quadratic function in the interval is a comprehensive problem, which affects the position of the interval and the axis of symmetry in the interval of the quadratic function. In this paper, the interval and the symmetry of the axis are both static and dynamic. Classify changes and explore ways to find the best value.
