在二次函数优化问题的教学中,教师凭自己的教学经验,结合教材中的解法,容易形成定势思维:通过建立二次函数模型,化为顶点式的解析式或者化为一般式后利用公式,从而求出问题中的最值。
In the teaching of the quadratic function optimization problem, teachers can combine their own teaching experience with the solutions in the textbooks to easily form fixed-thinking thinking: by establishing a quadratic function model, it can be converted into a vertex-type analytical formula or transformed into a generic type. Formula to find the best value in the problem.
