If `f:[0,oo[vecR` is the function defined by `f(x)=(e^x^2-e^-x^2)/(e^x^2+e^-x^2),` then check whether `f(x)` is injective or not.

f: R->R is defined by f(x)=(e^(x^2)-e^(-x^2))/(e^(x^2)+e^(-x^2)) is :

The function f:RtoR defined by f(x)=e^(x) is

The inverse of the function f(x)=(e^(x)-e^(-x))/(e^(x)+e^(-x))

The inverse of the function f(x)=(e^x-e^(-x))/(e^x+e^(-x))+2 is given by

The range of the function f(x)=(e^x-e^(|x|))/(e^x+e^(|x|)) is

Let f:Rto R be a functino defined by f (x) = e ^(x) -e ^(-x), then f^(-1)(x)=

The function f(x) = e^(|x|) is

The inverse of the function f:Rto range of f, defined by f(x)=(e^(x)-e^(-x))/(e^(x)+e^(-x)) is

Let f : R->R be a function defined by f(x)=(e^(|x|)-e^(-x))/(e^x+e^(-x)) then --(1) f is bijection (2) f is an injection only (3) f is a surjection (4) f is neither injection nor a surjection

If the function of f:R->A is given by f(x)=(e^x-e^(-|x|))/(e^x+e^(|x|)) is surjection, find A
