Hey everyone, for homework we have to have one example of each under the condition that A = {odd numbers} and B = {even numbers}, thus:

give examples of functions from A to B which are:

a) One-to-one but not onto

b) Onto but not one-to-one

c) Neither one-to-one nor onto

d) One-to-one and onto

I've been working at this and I can't seem to get even the simplest of examples, ugh. Thanks for the help!
