近年来,函数图象的表现形式的直观效果以及内涵特征的丰富性使其在全国各地的中考中受到青睐。关于函数图象的考查,一种是通过分析已知信息进行函数图象的确定,另一种是通过对函数图像的分析,对其隐含信息进行挖掘,即已知信息→确定图象,已知图象→挖掘信息。学生在函数图象的实际操作处理过程中,常会在函数图象和数学信息的互译出现部分差错,从而导致最终结果的不正确性。因此,通过对函图象的解读,促进学生解决函数问题的能力提高,进一步提高学生的数学思维水平。
In recent years, the visual effects of functional images and the richness of their connotations make them popular in the senior high school entrance examinations throughout the country. On the function of the image of the test, one is through the analysis of known information to determine the function of the image, the other is through the analysis of the function of the image, its hidden information mining, known information → determine the image, Known Image → Mining Information. Students in the actual operation of the function image processing, often in the functional image and mathematical information of the translation part of the error, resulting in the final result of the incorrect. Therefore, through the interpretation of correspondence images, the ability to promote students to solve the functional problems to improve and further improve the level of students’ mathematical thinking.
