若函数y=1/(2x+1)(x>0)与函数y=f(x)的图像关于y=x对称,则f(x)=__

若函数y=1/(2x+1)(x>0)与函数y=f(x)的图像关于y=x对称,则f(x)=__
若函数y=1/(2x+1)(x>0)与函数y=f(x)的图像关于y=x对称,则f(x)=__

若函数y=1/(2x+1)(x>0)与函数y=f(x)的图像关于y=x对称,则f(x)=__
关于y=x对称
则是反函数
x>0
2x+1>1
0<1/(2x+1)<1
所以f(x)定义域是0y=1/(2x+1)
2x+1=1/y
2x=1/y-1=(1-y)/y
x=(1-y)/(2y)
所以y=(1-x)/(2x),0

把y=1/(2x+1)中的x换为y,y换为x,所得 即是f(x) 【直接代换法】

in Wuqiao Acrobatics World,Oakley sunglasses, all of them show fantastic, hard to forget, but most are lovely, memorable people, or Mr. Wang Baohe -
thirty this year, Taiwan's Lu Chen magician performing shows in the spring night, a handful of shows, so you really experience the magic charm.
At this time, we're on the go Wei teachers volunteered to require changes in her hands. We hold your breath, staring at the elderly action, lest anything fall. I saw old people do not worry not alarmed, holding stick command, suddenly heard shouting
we propose the ball in question, and replaced with mineral water bottle. This should not miss it, the results of our eyes are still wrong.
Teacher Wei stunned, a variable two children.
Some people say we is not have authority under the table? Thus, we propose the withdrawal of the cloth, apart from anything else on the withdrawal of the elderly, come and go, with the result or we lose.
; ; wallpaper has been removed we are
It reminds me of
you please be patient to see, this film should give you benefited, which opened a casino Liu Qian Spring Festival Evening magic and the secret, the other just like this piece dedicated to gambling people, so you know how did you lose money, so we do not gamble advise! ! !

Like the gamble of all came in to see how you are losing money
In fact, Mr. Wang Baohe, there is another unique skills, shifty power. Yungong later, about 1.70 meters tall that he can wear a 2,3-year-old children's clothes. But the effort was too beverages, had finished a half months after the ten days to restore the Caixing. Currently, the shifty face lost power, mainly trained in the process extraordinarily difficult, the elderly fear of human transmission can not stand pain.

When the old man took a small bowl performances of two, three balls,Ray Ban sunglasses, while mutter prayers, while the three small balls with a stick in the bowl and pointing to the two, with his cries of , bowl the ball escape from missing, we do not always guess the number, we will never see eye when the real ending.

said that with 3 sets of CCTV cameras specifically Mr. Wang Baohe of Mr. Wang's fast chips in the rapidly visible.
Wuqiao Acrobatics World two years ago to see the devil's hands Mr. Wang Baohe performing any assistants, but also distance the audience hundred percent interactive.
