反函數(shù)的性質(zhì)有哪些
函數(shù)f(x)與它的反函數(shù)f-1(x)圖象關(guān)于直線(xiàn)y=x對(duì)稱(chēng);函數(shù)及其反函數(shù)的圖形關(guān)于直線(xiàn)y=x對(duì)稱(chēng);函數(shù)存在反函數(shù)的充要條件是,函數(shù)的定義域與值域是一一映射等。反函數(shù)性質(zhì):函數(shù)f(x)與它的反函數(shù)f-1(x)圖象關(guān)于直線(xiàn)y=x對(duì)稱(chēng);函數(shù)及其反函數(shù)的圖形關(guān)于直線(xiàn)y=x對(duì)稱(chēng);函數(shù)存在反函數(shù)的充要條件是,函數(shù)的定義域與值域是一一映射的。
