近年来,图形类反比例函数类的中考问题越来越受到命题者的喜欢,究其原因是,反比例函数考查中更加注重对于图形的理解和应用,重点考查学生理解和运用数学知识的能力,并突出了数学思想方法的考查,尤其是数形结合思想的考查,下面先来看一个中考实例:例1(2015年内江)如图1,正方形ABCD位于第一象限,边长为3,点A在直线y=x上,点A的横坐标为1,正方形ABCD的边
In recent years, the graphic inverse function of the class in the test questions more and more like by the proponents, the reason is that the anti-proportional function test pay more attention to understanding and application of graphics, focusing on the ability of students to understand and use mathematical knowledge, and Highlighting the mathematical method of thinking, especially the number of combination of ideological examination, the following first look at a senior high school entrance examination examples: Example 1 (2015 Neijiang) Figure 1, the square ABCD in the first quadrant, the side length of 3, point A On the line y = x, the abscissa of point A is 1, the side of the square ABCD
