函数图象是研究函数性质的基础,也是运用数形结合思想解题的基础,因此在中考中对函数图象的考查频率极高,几乎年年必考.其类型主要有:⒈给情定图;⒉给图定情;⒊给图定式;⒋给式定图;⒌自觉利用图象解题(数形结合);⒍有关的综合问题.本文试以近几年的中考试题为例,对中考函数图? Functional images are the basis for the study of the nature of functions, and they are also the basis for solving problems using the combination of numbers and shapes. Therefore, the frequency of examination of functional images in high school entrance examinations is very high, and almost every year must be tested. The types of these are: 1. Fig. 2. Picture given; 3. Graph given; 4. Given graph; 5. Conscious use of image problem solving (numerical combination); 6. Comprehensive questions. This article takes the middle exam in recent years as an example. The test function chart?
