反比例函数是初中阶段非常重要的函数关系之一,近年各地中考试题中经常出现以直线和双曲线为背景的图形面积问题,本文举例谈谈如何解决这种类型的问题.一、利用系数k与面积间的关系这里k是反比例系数,利用k的几何意义可以解决一类面积问题.如图1,设点P(x0,y0)为反比例函数y= The inverse proportion function is one of the very important function relations in the junior middle school stage. In recent years, the problem of the graphic area with the straight line and the hyperbola often appears in the middle school exam questions. This article gives an example to talk about how to solve this type of problem.First, The relationship between the area where k is the inverse proportion coefficient, the use of the geometric meaning of k can solve a class of area problem shown in Figure 1, set point P (x0, y0) for the inverse proportion function y =
