文[1]介绍了已知函数值域求参数取值范围的题目的两种解法,其中,采用对比的方法,探讨了学生的一种“秒杀”解法的错误之存在,指出了这种“秒杀”解法的缺陷.然而,读完全文,竟然有一些困惑,写出来与大家交流.思考一:“秒杀”错解的原因是什么?细心读完全文,并没有在文[1]的字里行间找到“秒杀”错解的本质原因.文[1]中只是简单地归结为“非等价转化”.“非等价转化”只是一个笼统的说法, In [1], we introduce two solutions to the problem of determining the value range of parameters in the range of known functions, in which a contrasting method is used to explore the existence of a “” spike “ However, after reading the full text, even some confusion, write out to communicate with you.Review a: ”spike “ wrong solution is what? Carefully read the full text, there is no In the text [1] between the lines to find ”spike “ wrong solution of the nature of the reason .In [1] is simply attributed to ”non-equivalent conversion “. ”Non-equivalent conversion " is just a general statement ,
