函数性质在解决函数问题中至关重要,函数的奇偶性是函数的重要性质,是解决函数问题的强有力工具.有些问题从表面上看似乎与函数无关,如果我们从已知所给出的式子的结构特征入手,站在函数的角度审视问题并抓住问题的本质,创造性地构造奇函数并运用奇函数性质来处理问题,往往可达到“山重水复疑无路,柳暗花明又一村”的解题境界.下面着重 The nature of the function is crucial in solving the problem of the function, whose parity is an important property of the function and is a powerful tool for solving the problem of the function. Some problems appear to have nothing to do with the function on the surface. If we know from the given Starting from the structural features of the formula, we can look at the problem and grasp the essence of the problem from the perspective of the function, construct the odd function creatively and deal with the problem by using the properties of the odd function, often reaching the point of “ Village ”problem-solving realm
