4) [9] Let A = {-3,-2,-1,0,1} and B = {-8,-6,0,6,10}. Define g: A B by g(x) = 2x - 8. a) What is the codomain of g? b) What is the range of g? c) What is the domain of g? d) Is g injective? Explain why or give a SPECIFIC counterexample. e) Is g surjective? Explain why or give a SPECIFIC counterexample. f) Is g bijective? Explain why or give a SPECIFIC counterexample. 4) [9] Let A = {-3,-2,-1,0,1} and B = {-8,-6,0,6,10}.
