Nettet14. nov. 2012 · 1 Answer Sorted by: 1 Notice that if there are distinct b 1, b 2 ∈ B such that f ( b 1) = f ( b 2), you won’t necessarily be able to cancel f: there might be some a ∈ A such that g ( a) = b 1 and h ( a) = b 2, but you’d still have ( f ∘ g) ( a) = ( f ∘ h) ( a). Thus, you want f to be injective (one-to-one). Can you prove that that’s sufficient? inland surf bairnsdale
