纵观近几年试题的走向,利用数形结合思想解决函数问题是中考答题中的一个重要技巧,以下以几个典型题目为例说明此类考题的答题策略. [例1](2008广州)如图1,一次函数y_1=kx+b的图象与反比例函数y_2=m/x的图象相交于A、B两点.
Taking a look at the trend of test questions in recent years, the use of mathematical combination of ideological function to solve the problem is an important one of the skills in the test, the following several typical topics as an example to illustrate the answer to such questions. [Example 1] (2008 Guangzhou) As shown in Fig. 1, the image of the linear function y_1 = kx + b and the image of the inverse proportion function y_2 = m / x intersect at points A and B.
