一、命题趋势对反比例函数基本知识和技能的考查较为普遍,反比例函数的应用型问题、反比例函数与一次函数及其它知识的综合解决问题经常都以中档题呈现,特别是最后一小问综合性强,知识覆盖面广,难度大,对学生要求高.二、存在问题(1)反比例函数增减性的理解有漏洞;(2)反比例函数图像的识别能力欠缺; First, the trend of proposition The basic knowledge and skills of the inverse proportion function test is more common, the inverse proportion function of the application type, inverse function and a function and other knowledge to solve the problem are often presented in mid-range problems, especially the last minute comprehensive Second, the existing problems (1) There is a loophole in the understanding of the inverse proportion function addition and subtraction; (2) The recognition ability of the inverse proportion function image is deficient;
