函数问题,是高考命题的核心问题之一.一般来说,高考中的函数问题综合性强,难度大,此类问题不仅考查了丰富多彩的函数知识,同时考查了考生的分析问题和解决问题的综合能力和创新能力.面对纷繁复杂的函数问题,我们该怎么办?转化与化归是“王道”!一、将数学表达式等价转化例1.已知f(x)为定义在实数集R上的奇函数,f(x)且 Function problem is one of the core issues of college entrance examination propositions.Generally speaking, the function of the college entrance examination in a comprehensive and difficult, such a problem not only examines the rich and colorful function of knowledge, while examining the examinee’s analysis and problem solving The comprehensive ability and ability to innovate. Faced with complex function problems, what should we do? Transformation and transformation are “Wang!” First, the mathematical expression equivalent conversion Example 1. Known f (x) is Define the odd function on the real set R, f (x) and
