If 2f((1)/(x))+f(x)=3x , find f(x-(1)/(x))

If f(x)=2^x the f(x+3)/ f(x-1) =?

If f(x)=(1+x)/(1-x), show that: f(2x)=(3f(x)-1)/(3-f(x)) .

A polynomial function f(x) satisfies the condition f(x)f((1)/(x))=f(x)+f((1)/(x)) for all x in R,x!=0. If f(3)=-26, then f(4)=

If f(x).f((1)/(x))=f(x)+f((1)/(x)) , and f(3)=82, then int(f(x))/(x^(2)+1)dx=

If : 3f(x)-2f((1)/(x))=x," then: "f'(2)=

If f(x)=(x-1)/(2x^(2)-7x+5) for x!=1 and f(x)=-(1)/(3) for x=1 then f'(1)=

IF f(x) = ( x+2)/(3x-1) , then f(f(x)) is

If f(x) = (x+2)/(3x-1) then f (f(x)) is

Let f :R -{(3)/(2)}to R, f (x) = (3x+5)/(2x-3).Let f _(1) (x)=f (x), f_(n) (x)=f (f _(n-1) (x))) for pige 2, n in N, then f _(2008) (x)+ f _(2009) (x)=
