If `f(x)=x/(x-1)`, then `(fofofo......of)(x)` is equal to

If f(x)=(x+1)/(x-1)(x!=1) then fofofo f(x)=

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

If f(x)=x^(3)+(1)/(x^(3)), then f(x)+f((1)/(x)) is equal to

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

If f(x) = 1/(1-x) , then f(f(f(x))) is equal to

If f(x)=(1-x)/(1+x), then f((1-x)/(1+x)) is equal to

If f(x)=(1)/(1-x), then f(f(f(x))) is equal to

If f(x)=(x)/(x-1) , then what is (f(a))/(f(a+1)) equal to?

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))
