若函数y=f(x)满足f(x)=f(1/x)lgx+1,求f(10)的值

对于任意整数x,y,函数f(x)满足f(x+y)=f(x)+f(y)+xy+1,若f(1)=1,则f(8)等于 对于任意整数x,y函数f(x)满足f(x+y)=f(x)+f(y)+xy+1.若f(1)=1.那么f(-8)等于? 若函数y=f(x),满足f(x+1)=2f(x),求f(x) 若一次函数f(x)满足f[f(x)]=1+4x,求f(x) 若一次函数f(x) 满足f[f（x)]=1+2x 求f(x) 若函数y=f(x)满足f(x)=f(1/x)lgx+1,求f(10)的值 函数f(x) 满足关系f(xy)=f(x)+f(y),x,y属于R,求f(1); 函数f(x)满足关系f(xy)=f(x)*f(y)(x,y属于R）求f(1) 已知函数f(x)满足：f(1)=1/4,4f(x)f(y)=f(x+y)+f(x-y),则f(2015)= 已知函数f(x)满足f(1)=1/4,f(x)+f(y)=4f(x+y/2)*f(x-y/2)则f(-2011)=? 已知函数f(x)满足,f(1)=0.25,4f(x)f(y)=f(x+y)+f(x-y) 则f（2010）= 已知函数f(x)满足f(2)=1/2,2f(x)f(y)=f(x+y)+f(x-y),则f(2012)=? 已知函数f(x)满足:f(1)=0,f(x)f(y)=f(x+y)+f(x-y),则f(2014)= 已知函数f(x)满足:f(1)=1/4,4f(x)f(y)=f(x+y)+f(x-y).则f(2010) 已知函数f(x)满足f(3)=1/3,3f(x)f(y)=f(x+y)+f(x-y),求f(1812) 若函数f(x)满足f(x+y)=f(x)+f(y) (x,y∈R)证明f(-x)f(x) 高中数学函数题已知函数f(x)满足：f(1)=1/4,4f(x)f(y)=f(x+y)+f(x-y) (x,y属于R),则f(2010)=?已知函数f(x)满足：f(1)=1/4,4f(x)f(y)=f(x+y)+f(x-y) (x,y属于R),则f(2010)=? 已知函数y=f(x)满足f(-2)>f(-1),f(-1)
