奇偶性和单调性是函数的两种重要特性,是高考的重点和热点.高考试题从早些年代的具体考查发展到现在的抽象考查,从单一考查发展到综合考查,从对判断、证明的考查发展到对应用的考查.这种发展的趋势很明显,就是对灵活性的要求在逐步提高,对能力的要求在逐步提高.本文不可能涉及这部分知识的所有内容,只能择其要点略作分析,希望同学们多少能有些领悟.
Parity and monotonicity are two important characteristics of the function and are the focus and hotspot of the college entrance examination. The examination questions are developed from the specific examinations in the earlier years to the current abstract examinations, from single examination development to comprehensive examination, from the judgment and proof. The examination has evolved into the examination of applications. The trend of this kind of development is obvious, that is, the requirement for flexibility is gradually increasing, and the requirements for competence are gradually increasing. This article cannot involve all the contents of this part of the knowledge, but can only select its main points. Slightly analyzed, I hope that the students can understand how much.
