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.

If f:[0,oo]toR 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.

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