反比例函数y=k/x(k≠0且k为常数)反映的是两个变量之间的一种反比例关系.反比例函数的性质与其图象、比例系数k密不可分.因此反比例函数的性质是学习反比例函数的重点和难点;同时也是考查反比例函数的核心考点.下面说说反比例函数的性质及应用.
The inverse proportional function y=k/x (k≠0 and k is a constant) reflects an inversely proportional relationship between the two variables. The properties of the inverse-proportional function are inseparable from the image and the proportionality coefficient k. Therefore, the nature of the inverse-proportional function is Learn the key and difficult points of the inverse proportion function; at the same time, it is also the core test point for examining the inverse proportion function. Here we talk about the nature and application of the inverse proportion function.
