Thank you so much iMac in the university in Yemen and my mother language is Arabic I couldn't understand this topic in everywhere I I have searched a lot list of it in Arabic but I couldn't find it so I said in English language that would make your video shouted to me and this is very amazing because I know everything's in English is very well this my way and I couldn't find anything❤❤❤❤❤

Very clear now, thx!

thank you, very helpful

It makes so much sense now :D

wonderful, now i understand very clearly, thank you.

Thanks

Thank you

insert really nice appreciative comment here for assisting my discrete math course, making the material a lot easier and fruitful

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.

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.

Thanks for the great videos Professor Brehm! You really helped me pass the exam!

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!
