Thank you for making it so simple for us! You literally save me. DM looked so scary and I was worried that I will fail my exam, now I am confident that I will pass it. Thank you for your efforts Professor Brehm!
Thank you! I absolutely would not be able to make it through this class without your lectures
I was literally having a nightmare trying to understand functions but you made it 10x easier, THANK YOU from the bottom of my heart for this.
I really like this updated version, the added content clarifies a lot better than original!
Thanks for the great videos Professor Brehm! You really helped me pass the exam!
fantastic series. Thank you!
Great series! Thank you so much!!!
Thank you sooooo much, like seriously, this helped so much
You lost me with the last question. Great content though.
wonderful, now i understand very clearly, thank you.
Thank you so much Professor. You make every explanation so easy to understand. It's so nice to learn from a professor who actually cares! You are an inspiration. I am in my first semester of univerversity and Comp 232 has been getting overwhelming for me. I don't understand my professor, the book take so long to read, and its hard to find and search up every topic on youtube. Your videos have been helping me in learning discrete Mathematics sequencially and easily. Good bless you, Professor Brehm. You are literally saving me!

Well done
Suppose let function is x^2 what if -2 and 2 both maps to 4 in co domain... -2 and 2 are different numbers but maps to same value. You said if two values from domain maps to same value in co domain then those 2 values in domain must be same which is not in this case Edit : what the hell. I think youu read people's mind. Within a minute of posting the question, my doubt is solved in later video.
Best explaination

There are now closed captions so you can turn them on and then auto-translate them. I know other languages to Engish usually works pretty well including Hindi-> English so I expect this work around could work if you're willing to read it.
