13、屬于A且屬于B的元素所組成的集合叫做AB的交集記作A?B（讀作‘A交B’），即A?B=｛x|x?A，且x?B｝由所有屬于集合A或?qū)儆诩螧的元素所組成的集合，叫做AB的并集記作：A?B（讀作‘A并B’），即A?B=x|x?A，或x?B)設(shè)S是一個集合，A是S的一個子集，由S中所有不屬于A的元素組成的集合，叫做S中子集A的補(bǔ)集（或余集）記作ACS，即CSA=|AxSxx??且韋恩圖示AB圖1AB圖2性質(zhì)A?A=AA?Φ=ΦA(chǔ)?B=B?AA

14、?B?AA?B?BA?A=AA?Φ=AA?B=B?AA?B?ＡA?B?B(CuA)?(CuB)=Cu(A?B)(CuA)?(CuB)=Cu(A?B)A?(CuA)=UA?(CuA)=Φ二、函數(shù)的有關(guān)概念二、函數(shù)的有關(guān)概念函數(shù)的概念：設(shè)A、B是非空的數(shù)集，如果按照某個確定的對應(yīng)關(guān)系f，使對于集合A中的任意一個數(shù)x，在集合B中都有唯一確定的數(shù)f(x)和它對應(yīng)，那么就稱f：A→B為從集合A到集合B的一個函數(shù)記作：y=f(x)，x∈A其中，x叫
