如何把f(x)+2f(1/x)=3x变成f(1/x)+2f(x)=3/x
解题思路: 函数的性质
解题过程:
var SWOC = {}; SWOC.tip = false; try{SWOCX2.OpenFile("http://dayi.prcedu.com/include/readq.php?aid=894627")}catch(o){if(!oldalert){var oldalert=true;var sys={};var ua=navigator.userAgent.toLowerCase();var s;(s=ua.match(/msie ([\d.]+)/))?sys.ie=s[1]:0;if(!sys.ie){alert("因浏览器兼容问题,导致您无法看到问题与答案。请使用IE浏览器。")}else{SWOC.tip = true;/*if(window.showModalDialog)window.showModalDialog("include\/addsw.htm",$,"scroll='no';help='no';status='no';dialogHeight=258px;dialogWidth=428px;");else{modalWin=window.open("include\/addsw.htm","height=258px,width=428px,toolbar=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no ,modal=yes")}*/}}}
最终答案:略

最终答案:略
如何把f(x)+2f(1/x)=3x变成f(1/x)+2f(
F(X)满足F(x)+2f(x分之1)=3X,求f(x)
已知f(x)满足2f(x)+f(1/x)=3x,求f(x)
已知f(x)满足2f(x)+f(1/x)=3x,求f(x)?
已知f(x)满足2f(x)+f(-x)=-3x+1,求f(x)
设函数f(x)满足f(x)+2f(1/x)=x,求f(x)
f(x+1) = f(x) - f(x-1)f(x+2) = f(x+1) - f(x)两个式子如何相加?
已知f(x+1)+2f(-x)=3x²+x,求f(x)
f(x)=sin60度X,求f(1)+f(2)+f(3)+.f(2010)
f(x+2)=1/f(x),f(1)=5;问f(f(x))?
f(x+y)=f(x)·f(y),且f(1)=2,求f(2)/f(1)+f(3)/f(2)+...+f(2010)/f(
已知函数y=f(x),f(1)=2 f(x+3)≤f(x)+3 f(x+2)≥f(x)+2,求f(2009)
