Prove or disprove:
For all functions f: A -> B and g: B -> C, if g: B -> C
is injective and f: A -> B is surjective, then the composition
function : A -> C is
injective.
For all functions f: A -> B and g: B -> C, if g: B -> C
is injective and f: A -> B is surjective, then the composition
function : A -> C is
injective.
