Classification method of thinking and thinking is one of the basic methods of high school mathematics, is the focus of college entrance examination over the years .Using this method to solve problems requires a certain degree of analytical skills and classification skills .Study students are required to pay attention to the application of the classification of thinking at the same time, But also to avoid the parameters to discuss, should establish a dialectical problem-solving point of view so that the classification discussion is more reasonable.How to simplify or avoid classification discussion, this article takes the function problem as an example
