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

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

If f: R to R defined by f(x) =(e^(x^(2)) -e^(-x^(2)))/(e^(x^(2)) +e^(-x^(3))) , then f is

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.

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

Let f:R rarr R" be defined by "f(x)=(e^(|x|)-e^(-x))/(e^(x)+e^(-x)). Then

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.

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 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[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.
