函数是中学数学中的核心内容,也是高等数学中基础的知识.作为选拔性考试———高考对其时有涉及.而且考查的方式逐年变化.本文将对近年(尤其是2005年)悄然兴起的分段函数进行点析.1图象分段类这类题多是指出函数表达式,要求选出符合条件的图象;或者给出函数图象要求学生确定符 Function is the core content of high school mathematics, but also the basic knowledge of higher mathematics.As a selective examination - college entrance examination for the time being involved.And the way to examine changes year by year.This paper will quietly rise in recent years (especially in 2005) Of the segmentation function analysis.1 Image Segmented class Most of these questions are pointed out that the function expression requires the selection of qualified images or given the function image requires the student identifier
