Directions: Read each statement carefully, show your complete solution if needed.
1. Write out all functions f: (1,2,3) – (a,b) (using two
- line notation). How many Function are there? How many are surjective? How many are bijective?
2. For each function give below. Determine whether or not the function in injective and whether or not the function is surjective.
(a) f: N – N given by f(n) = n + 4
(b) f: Z – Z given by f(n) = n + 4
(c) f: Z – Z given by f(n) = 5n – 8
