`f(x) = 9^x/ ( 1 + 9^x)` then value of `f(1/2015) + f(2/2015) .......+ f(4029/2015)`

f(x) = 9^x/ ( 9 + 9^x) then value of f(1/2015) + f(2/2015) .......+ f(4029/2015)

If f(x+1)=3x-9,then value of f(x^2-1) is

If f(x)=(x+1)/(x-1) , then the value of f(f(2)) is

Let f(x)=(9^(x))/(9^(x)+3) then find the value of f((1)/(2006))+f((2)/(2006))+f((3)/(2006))+...+f((2005)/(2006))

IF f(x)=(9^x/(9^x+3)), then f(1/2012)+f(2/2012)+...+(2011/2012) is equal to

let f(x)=(9^(x))/(9^(x)+3)then f(x)+f(1-x)

If f(x)=(9^(x))/(9^(x)+3) then f((1)/(1996))+f((2)/(1996))+.......+f((1995)/(1996))=

Let f:RrarrR be differentiable at x=0 . If f(0)=0 and f'(0)=2 ,then the value of lim_(xrarr0)1/x[f(x)+f(2x)+f(3x)+.....+f(2015x)] is

If f(x)=(9^(x))/(9^(x)+3) then f((1)/(1996))+f((2)/(1996))+...+f((1995)/(1996))=
