- Abstract Functions And Start Of Linear Transformations Given F A B And G B C Is It True That If Go F Is Surjec 1 (41.33 KiB) Viewed 36 times
Abstract functions and start of linear transformations • Given f : A + B and g: B → C, is it true that if go f is surjective, then f is surjective? Prove this or provide a counterexample. • Prove that if f : A + B is injective and g: B + C is injective then gof: A + C is injective. • Let f :R" + R" be a linear transformation. Prove that f is injective if and only if the only vector v ER" for which f(u) = 0 is v = 0.
