二次函数解析式的确定

To Determine Analytic Expressions of the Quadratic Function

确定二次函数解析式,归根结底就是确定解析式中的变量项的系数及常数项,本文根据五种已知条件列举了五种确定二次函数解析式的方法。

To determine analytic expressions of the quadratic function is, in the final analysis, to determine it's coefficients of variable terms and constant. Five methods to determine analytic expressions of the quadratic function in accordance with five types of known conditions are introduced in the article.
