WebOct 2, 2016 · If A is a singleton then g: A → B and f ∘ g: A → B are automatically one-to-one. Now let B have more than one element, and let f be constant. Then f is not one-to-one. Actually f ∘ g one-to-one alone ensures g is one-to-one. Proof by contrapositive: if g is not one-to-one, f ∘ g can't be one-to-one. WebMay 11, 2016 · For any two functions $f (x)$ and $g (x)$ we are given $f \circ g = g \circ f$. What does this imply?
