求解二次函数解析式是中考中较为常见的题型,其求解方法要依据题给条件的不同,灵活多样的进行求解.下面就此类问题的求解方法归纳如下,希望能够对同学们有所帮助.一、三点型若已知抛物线上三点的坐标,则可用一般式y=ax~2+bx+c.例1已知一个二次函数的图象经过(-1,10)、 Solving the quadratic function analytic formula is more common in the test questions, and its solution to be based on the conditions given to the different, flexible and diverse to solve. The following solution to these problems are summarized below, hoping to be able to help students First, the three point type If you know the coordinates of the three points on the parabola, you can use the general formula y = ax ~ 2 + bx + c Example 1 known a quadratic function of the image through (-1,10),
