"WebThe composition of injective functions is injective and the compositions of surjective functions is surjective, thus the composition of bijective functions is bijective. That is, let f:A → B f: A → B and g:B → C. g: B → C. If f,g f, g are injective, then so is g∘f. g ∘ f. If f,g f, g are surjective, then so is g∘f. g ∘ f. " - Surjective and bijective

Webfrom being bijective: the range of f is only a single point {π}, so f is not surjective, whereas g maps every real number to 0, so is not injective. On the other hand, something is true: namely the “inside function” f is injec- tive, and the outside function g is surjective. This is in fact a general phenomenon. Theorem 2.
