Determine if each of the following relations is a functions with domain A={1,2,3,4} and codomain B ={a,b,c,d}. Give a brief reason. %3D (1) f = {(1,d),(2,d),(3,b)} . (2) g = {(1,d),(2,c),(3,c), (3,a),(4, d)}.

Which of the following are one-to-one functions? OS = {(4, – 3), (1, 7), ( – 4, – 5), ( – 1, – 1), (10, 8), (6, – 6)} OF = {(- 2, – 1), (0, 0), (3, 2), (6, 5), (8, 7), (10, 12)} %3D OM = {(0, – 5), (3, 2), (3, 5), (6, 7), (9, – 6), (12, 13)} %3D OR= {(- 2,0), (2, 1), (4, 6), (7, 8), (11, 10), (14, 16)} OG = {(– 1, 2), (6, – 1), (1, – 2), (4, 0), (10, 1), ( – 5, – 1)} | Question Help: Message instructor Submit Question
