Question

函數(shù)的圖像關(guān)于 (       )

A．軸對(duì)稱

B．直線

C．坐標(biāo)原點(diǎn)對(duì)稱

D．直線

Answer 1

C

解析試題分析：函數(shù)圖像關(guān)于軸對(duì)稱則是偶函數(shù),函數(shù)圖像關(guān)于直線對(duì)稱則反函數(shù)是它本身, 函數(shù)圖像關(guān)于坐標(biāo)原點(diǎn)對(duì)稱是奇函數(shù)
由得
又因?yàn)?img src="http://thumb.zyjl.cn/pic5/tikupic/80/2/pnemo2.png" style="vertical-align:middle;" />的定義域是關(guān)于原點(diǎn)對(duì)稱,所以是奇函數(shù),所以圖像關(guān)于坐標(biāo)原點(diǎn)對(duì)稱
故選C
考點(diǎn)：函數(shù)的奇偶性, 函數(shù)的對(duì)稱性.
