函数的基本性质主要包括函数的单调性、奇偶性、周期性的研究及定义域、值域、最值的探求.与函数的性质有关的竞赛试题主要表现为各种性质之间的综合以及各种性质与其他知识(如方程、不等式、三角、数列、几何、导数等)的交汇,解题时应注意综合理解、分析问题的本质,充分挖掘题 The basic properties of the function include monotonicity, parity, periodic research and domain definition, the value of the search. The questions of the nature of the function of the competition mainly for the nature of the integration between the various and each The nature and other knowledge (such as equations, inequalities, trigonometry, series, geometry, derivatives, etc.) of the intersection of problem solving should pay attention to comprehensive understanding of the nature of the problem, fully tap the questions
