If f(x) and.g (x) are two functions with `g(x)=x-1/x` and `f(g(x))=x^3-1/x^3` then `f(x)` is

If f(x) and g(x) are two functions with g (x) = x - 1/x and fog (x) =x^(3) -1/x^(3) then f(x) is

If f(x) and g(x) are two real functions such that f(x)+g(x)=e^(x) and f(x)-g(x)=e^(-x) , then

Suppose that g(x)=1+sqrt(x) and f(g(x))=3+2sqrt(x)+x, then f(x) is

If f and g are two functions defined by f(x)=sqrt(x+1) and g(x)=1/x then find the following functions: f+g

If f and g are two functions defined by f(x)=sqrt(x+1) and g(x)=1/x then find the following functions: f-g

If f and g are two functions defined by f(x)=sqrt(x+1) and g(x)=1/x then find the following functions: f/g

If f and g are two functions defined by f(x)=sqrt(x+1) and g(x)=1/x then find the following functions: 2f-3g

Let f(x) and g(x) be two functions given by f(x)=-1|x-1|,-1 le x le 3 and g(x)=2-|x+1|,-2 le x le 2 Then,

If f(x)=3x+1 and g(x)=x^(3)+2 then ((f+g)/(f*g))(0) is:
