Talk:Math 360, Fall 2021, Assignment 2
Changes (Michael Reilly)[edit]
Most of the changes to the definitions I did were minor grammar changes or modifying TeX formulas and markup formatting, just to make answers easier to read. The only substantive change I made was to codomain and image, because the definitions were backwards: the codomain of a function is all possible values, the image of a function are the elements of the codomain specifically mapped to.
More Changes:[edit]
I am going through the answers, and some of them were wrong. For Section 0, problem 12, the confusion between codomain and image from the definitions section carried over and several of the functions were incorrectly noted as “onto” when they were not.
I cleaned up the formatting and readability of the answers for the rest of the book questions. I thought the answer to 29 was incorrect, but it was not, I was, I am reverting it now.
