    Bijection functions and inverses

    How can one prove that if a function is bijective then it has an inverse function?

    Say you have a function:

    f: x \to y

    And you then have a function which is the inverse relation of f, then it should be enough to prove that the inverse is bijective, because since f is the inverse relation of its inverse, f will automatically be bijective.
