一、现阶段下对于高中数学中函数的解题技巧认识与应用的现状1.对于高中函数的认识误区仍旧存在高中函数是基于初中函数知识上的延伸和拓展,它主要针对的两个变量不再是x与y之间的简单关系了,而是演变成了在一定的变换法则f的作用下两个集合之间的对应关系,这是对于函数知识的扩展,是囊括了除去空集之外的一种集合的对应关系.这种对应关系在特定的f法则下由两个变量的相互对应表现出来,比如:f(x)=log2(x2-1)的形式.想要正确的认
First, at this stage for high school mathematics function problem solving skills understanding and application of the status quo for high school function misunderstanding still exists High school function is based on the junior high school function knowledge extension and expansion, it is mainly aimed at the two variables are not Then the simple relationship between x and y, but evolved into the corresponding relationship between the two sets under the influence of a certain transformation law f, which is an extension of the knowledge of the function, is included to remove the empty set The corresponding relationship between a set of relations under the specific f law by the two variables correspond to each other, such as: f (x) = log2 (x2-1) in the form.
