抽象函数问题着重考查学生的逻辑思维能力和抽象概括能力,但是由于没有给出解析式,问题比较抽象,函数性质隐而不露,学生常常束手无策。本文结合实例阐述了针对问题的具体情况灵活求解的方法,指出其关键在于培养学生多角度思维的能力。 Abstract function problems focus on examining students’ logical thinking ability and abstraction ability, but students often do nothing because they do not give an analytical formula, the problem is rather abstract, and the nature of the function is hidden. In this paper, an example is given to illustrate the method of solving problems flexibly, pointing out that the key lies in cultivating students’ multi-angle thinking ability.
