近年来在全国高考与各地的模拟考试中,对于分式函数的考查越来越受到青睐。我们把形如f(x)=p(x)/q(x)的函数叫做分式函数,其中p(x)、q(x)是既约整式且q(x)的次数不低于一次。而学生在遇到分母在带有自变量的函数的问题时,总是感觉无从下手。那么如何求解分式函数中的相关问题,下面就它的解题方法与策略进行简单地归纳与说明。一、适度拓宽知识点,提高解题效率在中学数学学习的基本初等函数中,仅有反比例函数的分母中带有变量,而反比例函数又不是高中数学学习的主要内容,因此适度拓宽学生的知识面,可以有效地提高学生 In recent years in the national college entrance examination and around the simulation test, the test for fractional function more and more favored. We call a function of the form f (x) = p (x) / q (x) as a fractional function where p (x) and q (x) are both integers and q (x) . Students, however, often feel impassable in the face of problems with denominators over functions with independent variables. So how to solve the related problems in the fractional function, the following on its problem-solving methods and strategies are briefly summarized and explained. First, the appropriate broaden the knowledge points to improve the efficiency of problem solving In the basic elementary functions of mathematics learning in secondary schools, only the inverse proportion function denominator with variables, and inverse proportion function is not the main content of high school mathematics learning, so broaden students’ knowledge Face, can effectively improve students
