We have shown that the composition of two surjective functions is surjective, i.e. th if f : A → B and g : B → C are surjective, then go f : A → C is surjective. Now deci whether the following statements are true or false, and prove your claim. Remembe to prove that a statement is wrong, all you need to do is to give a counterexample. (i) If ƒ : A → B and g : B → C are functions such that go f is surjective, then f surjective. (ii) If f : A → B and g: B → C are functions such that go f is surjective, then 9 surjective. Get started by drawing some pictures of sets with arrows. No need to submit yo
