函数的图像是历年来高考的必考内容之一,经常以选择题、填空题的形式出现,主要涉及函数的零点、函数的性质、分段函数和导函数、三角函数等,也可能考查立体几何中图形的面积、体积及一些实际问题等,在考查函数知识的同时,又考查用函数思想、数形结合思想和分类讨论思想解决问题的能力。随着命题形式的多样化,高考试题中经常出现以图像为选项
The image of the function is one of the compulsory parts of the college entrance examination in the past years. It often appears in the form of multiple choice questions and blank filling questions. It mainly involves the zero point of the function, the nature of the function, the piecewise and derivative functions, the trigonometric functions and so on. Geometry in the area of the graphics, the volume and some practical problems, etc., while examining the function of knowledge, but also examines the function of thinking, the number of forms with ideas and the ability to discuss the problem of thinking. With the diversification of the form of proposition, the exam questions often appear as an image option
