If `f(x)=(3x-1)/(x+1),x!=-1,` then find `f@f(x).`

If f(x)=(x-|x|)/(|x|) , then find f(-1).

If f(x)= {4 - (x-7)^(3)} , then find f^(-1)(x)=

If f(x)=(x-1)/(x+1) , then f(f(a x)) in terms of f(x) is equal to (a)(f(x)-1)/(a(f(x)-1)) (b) (f(x)+1)/(a(f(x)-1)) (f(x)-1)/(a(f(x)+1)) (d) (f(x)+1)/(a(f(x)+1))

If f(x)=(x-1)/(x+1) , then show that f(1/x)=-f(x) (ii) f(-1/x)=1/(f(x))

If f(x)=(x-1)/(x+1) , then show that f(1/x)=-f(x) (ii) f(-1/x)=-1/(f(x))

If f: R->R is an odd function such that f(1+x)=1+f(x) and x^2f(1/x)=f(x),x!=0 then find f(x)dot

If f: R^+ to R , f(x) + 3x f(1/x)= 2(x+1),t h e n find f(x)

If f(x)=(1)/(3)x + 3 , then f^(-1)(x)=

If f(x)=x^(3)-(1)/(x^(3)) , then find the value of f(x)+f(-x) .

If f(x) = (x + 1)/(x-1) , then the value of f{f(3)} is :
