函数作为高中数学的一个重要组成部分,贯穿整个高中阶段的教学,在高考数学中有着举足轻重的地位与作用.函数是定义域与对应法则(解析式)构成的一个有机整体,常以解析式、图象、列表三种不同形式来呈现命题.其中,图象法直观形象,是一种重要的表示形式.下面笔者以2013年高考相关试题为载体,从识图、释图、用图三个方面分别进行归类分析,旨在探索高考中图象试题的题型规律及相应解题策略,以飨读者.

Function as an important part of high school mathematics, teaching throughout the high school has a pivotal position and function in college entrance examination math.Function is an organic whole consisting of domain and corresponding law (analytic) Image, the list of three different forms to present the proposition.Among them, the image of the visual image, is an important form of expression.The following author to take the college entrance examination in 2013 related questions as a carrier, from the knowledge map, release map, with the map three Respectively, classified analysis, aimed at exploring the image examination questions in the college entrance examination questions and the corresponding problem-solving strategies to readers.
