List all the functions from {1,2,3} to {1,2} representing each function as an arrow

diagram. Which of these functions are (a) injective, (b) surjective, (c) bijective? For

each surjective function write down a right inverse.

2. Relevant equations

3. The attempt at a solution

The only one I can think of is,

f(x) = x - 1, where X is all real numbers,

and in the directions it specifically asks for functionS...
