1、反比例函数-专题一知识要点、一般地，形如的函数称为反比例函数，比例系数为。其中，自变量x 的取值范围是。2、反比例函数的两种基本形式：3、反比例函数的图象名称是，它有个分支，它们关于对称；并且在每一象限内，随着x 的不断增大（或减小），曲线越来越坐标轴。但永远与坐标轴。4、反比例函数图象的性质：例 1.下列函数：31xy；xy5；xy52；)0(2aaxay为常数且；其中是反比例函数例 2.当 m=_时，函数22(1)mymx是反比例函数注意：kyx中的 k 例 3.若点（x1，y1）、（x2，y2）、（x3，y3）在反比例函数y=2x的图象上，若 x1x20 x3则下列结论中，正确的是（）A
2、y1y2y3By2y1y3Cy3y1y2Dy3y2y1y=kx(k0)图象k0 k0 性质1.图象在第 _ _象限；2.在每个象限内，函数y 随 x 的增大而1.图象在第 _ _象限；2在每个象限内，函数y 随 x 的增大而二反比例函数的对称性1、直线y=ax（a0）与双曲线 y=3/x 交于 A（x1，y1）、B（x2，y2）两点，则4x1y2-3x2y1=2、如图 1，直线 y=kx（k0）与双曲线 y=2/x 交于A，B两点，若 A，B两点的坐标分别为 A（x1，y1），B（x2，y2），则x1y2+x2y1的值为（）A、-8 B、4 C、-4 D、0 图1 图2 图3 三、反比例函数中
