同学们,现在让我们回顾一下高一数学都学了哪些内容,哪些比较重要,哪些比较难呢?“函数”肯定是其中最重要的内容之一,它甚至是整个高中数学最重要、最基础、考得最多的内容.本文重点带领大家复习一下函数应用题,同时也回顾一下,我们学过的基本初等函数模型.应用题往往文字较多,信息繁杂,因此阅读理解是解应用题的起点,审题时必须要对关键字、词、句式咬文嚼

Students, now let’s review what the first grade mathematics has learned. Which are more important and which are more difficult? “Functions” is certainly one of the most important contents. It is even the most important for high school mathematics as a whole. The most basic and the most studied content. This article focuses on leading you to review the function application problems, but also review the basic elementary function model we have learned. The application of the problem is often more text, information is complex, so reading comprehension is to solve the problem From the beginning, the keywords, words and sentences must be chewed
