if gof is one to one

Proof that if g o f is Injective(one-to-one) then f is Injective(one-to-one)

If gof is one one then f is one one | If gof is bisective then f is bisective | NumberX

Proof that if g o f is Surjective(Onto) then g is Surjective(Onto)

If gof is onto and g is one one then f is onto | If gof is surjective and g is bisective || NumberX

If gof is one one and f is onto then g is one one| if gof is Injective then f is Injective|| NumberX

If gof is onto then g is onto | If gof is surjective then g is surjective || NumberX

Proof: Composition of Injective Functions is Injective | Functions and Relations

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

Proof that if g o f is Surjective (Onto) then g is Surjective (Onto)
