设a属R,f(x)为奇函数,且f(2x)=(a*4^x+a^2)/(4^x+1),求f(x)的反函数?设g(x)=log根号下2((1+x)/k),若x属闭区间1/2到2/3闭区间时,恒有f-1(x)≤g(x)成立,求实数K的取值范围

I tend to realize that I had lost the West is not it beautiful ,mac eyeshadow, but the truth is the same : I have a West, I realized before losing some of their own What .
\x0d
I always : lose the West is the best, vanished is the most deep-seated feelings of the heart, the lover is the most perfect . We To all the good treasure , so one day regret it .
\x0d
Yes, some of the West , once lost, may not be heavy. However, the pros and cons of the candidates in the count , I think we have a son Do not know what you have lost ? if that person before , never know , the original I can find a better situation .
\x0d
If I had met ,mac brushes, and I never know why the situation before me , sacrifice, Bong and the original are , Today's encounter , I suddenly realize that before that period , the original is not the situation . I think former yearning and can not put people with hardly anything compared to the original . What a kind God , to understand the value of my all in all . Just one ,Ray Ban sunglasses, I never know what you have lost .
\x0d
However , some in the West destined ... how hard can not have . but I am as much a deep-seated heart. .. may have a good initial value of each other .
\x0d
but God met me in another ... I and re- fuel the fire ..\x0d
points from the day fixed , if at all , have also become , Hey can understand my mind ... the brave treasure with me .. I am the sub- . good?
