Given `f(x)=[1/3+x/66]`, then `sum_(x=1)^66f(x)` is

If f : R rarr R be given by: f(x) = (3-x^3)^1//3 , then f(f(x)) is:

If f:[1,oo)to[1,oo) is given by f(x)=x+(1)/(x) , then f^(-1)(x) equals :

If f:[1,oo)to[2,oo) is given by f(x)=x+(1)/(x) , then f^(-1)(x) equals :

Let f be a function satisfying f(x+y)=f(x) *f(y) for all x,y, in R. If f (1) =3 then sum_(r=1)^(n) f (r) is equal to

If f:RrarrR be given by f(x)=(3-x^(3))^(1//3) , then f^(-1)(x) equals:

If f : R rarr R be given by f(x) = (3 - x^3)^(1/3) , then (f o f) (x) is

If f: [1, oo) rarr [5, oo) is given by f(x) = 3x + (2)/(x) , then f^(-1) (x) =

f is a function such that f(x + y) = f(x) .f(y), forall x, y in R , if f(1) = 3, then find sum_(r = 1)^n f(r) .

If f is a function satisfying f(x+y)=f(x)f(y) for all x ,""""y in X such that f(1)=3 and sum_(x=1)^nf(x)=120 , find the value of n.
