WebA function f: R → R is even if f ( − x) = f ( x) for all x; it is odd if f ( − x) = − f ( x) for all x. Now consider f odd and g even: f ∘ g ( − x) = f ( g ( − x)) = f ( g ( x)), since g is even. But, by definition, f ( g ( x)) = f ∘ g ( x), so f ∘ g is even. A similar proof shows that g ∘ f is even. hermione x filch lemon
