反比例甬数是初中数学的重要知识点,也是各地中考命题的热点.考查的知识点主要有确定函数解析式、确定图象所在象限、比较函数值的大小、求代数式的值、确定函数的图象、与一次函数联姻、反比例函数的应用等.现精选几例,分类析解,供同学们学习时参考.考点1确定函数解析式例1(2014年南京)已知反比例函数的图象经
The inverse proportion of the number of Ningbo is an important knowledge of mathematics in junior high school, but also the hot spots around the test. The knowledge of the main test points to determine the analytical function to determine the image where the quadrant, compare the size of the value of the function, find the algebraic value, determine the function of the map Such as the marriage of a function, the application of inverse function, etc .. Now select a few examples, classification analysis, for students to learn reference point test center 1 to determine the function analytic Example 1 (Nanjing, 2014) known inverse proportion function of the image through
