The composition of two bijections is a bijection

The inverse of a bijection is also a bijection

If f and g are two bijections; then gof is a bijection and (gof)^(-1)=f^(-1)og^(-1)

The inverse of a bijection is unique

Let A = [-1, 1]. Which of the following functions on A is not a bijection?

A function f: R->R is defined as f(x)=x^3+4 . Is it a bijection or not? In case it is a bijection, find f^(-1)(3) .

Let A be any non-empty set.Then,prove that the identity function on set A is a bijection.

A function f is have inverse it should be a bijection

Classify f:R rarr R, defined by f(x)=sin x as injection,surjection or bijection.
