講函數(shù)的對(duì)稱(chēng)性主要是講奇偶函數(shù)圖像的對(duì)稱(chēng)性,函數(shù)與反函數(shù)圖像的對(duì)稱(chēng)性。前者是函數(shù)自身的性質(zhì),而后者是函數(shù)的變換問(wèn)題。下文中我們均簡(jiǎn)稱(chēng)為函數(shù)的對(duì)稱(chēng)性。函數(shù)的對(duì)稱(chēng)性在近幾年高考中屢見(jiàn)不鮮,對(duì)于解決其它問(wèn)題也很有幫助,同時(shí)也是數(shù)學(xué)美的很好體現(xiàn).現(xiàn)通過(guò)函數(shù)自身的對(duì)稱(chēng)性和不同函數(shù)之間的對(duì)稱(chēng)變換這兩個(gè)方面來(lái)探討函數(shù)對(duì)稱(chēng)性有關(guān)的性質(zhì)。
