Скачать или смотреть Functions (Set Theory)

In this video, we introduce the notion of functions using the set theoretic notion of a relation, including the related sets of domain, codomain, image, and pre-image. We consider some examples and nonexamples, and compare how notions of functions are presented before the usage of set theory.

This is lecture 30 of the lecture series offered by Dr. Andrew Misseldine for the course Math 3120 - Transition to Advanced Mathematics at Southern Utah University.
