函数奇偶性是函数的重要特征之一,它充分地体现了变量间的辩证统一关系.从数、形上揭示了函数的对称性.在解题过程中,深挖题目隐含条件,依据奇偶函数的性质,使一些问题独辟蹊径,解法简单化,有柳暗花明又一村之感.一、求函数的函数值 Function parity is one of the important features of the function, which fully embodies the dialectical unity between the variables.From the number, the shape reveals the symmetry of the function.In the process of solving problems, digging the implicit conditions of the topic, according to the parity The nature of the function, make some problems unique, the solution is simple, there is a sense of vista Another function of the function value
