If `f:RtoR^(+)` such that `f(x)=(1//3)^(x)`, the what is the value of `f^(-1)(x)`?

If f:RtoR,g:RtoRandg(x)=x+3and(fog)(x)=(x+3)^(2) , then what is the value of f(-3) ?

If f(x)=|x+1|-1 , what is the minimum value of f(x) ?

Let R be the set of real numbers and let f:RtoR be a function such that f(x)=(x^(2))/(1+x^(2)) . What is the range of f?

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

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

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

Let f:RtoR be defined by f(x)=x^(2)+1 , then the value of f^(-1)(17)andf^(-1)(-3) respectively are :

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