1. (5 pts) Given sets A = {a,b,c} and B-(p, q, r, s), define a function f : A B. If it is possible to make the function injective, then you must make it injective. If it is possible to make the function surjective, then you must make it surjective (a) Show your function using the graphical representation (arrow diagram). (b) Explain why the function is surjective or why it cannot be. (c) Explain why the function is injective or why it cannot be
