you explained it better than my teacher, when i asked him the difference between one to many and many to one he said it was the same thing, I wouldve went along with that if i hadnt came across this video, thank you
The domain is not 'an input', but the set of all possible inputs, i.e. the set of all possible x values which the function can take. The term 'codomain' is the set of all possible outputs, i.e. the set of all possible y values which the function can take. However, in IGCSE Add Math, we don't use this term - we use the word 'range' instead. So, for the function y = sqrt(x-1), the domain would be the set of all x values greater than or equal to 1, and the range (or codomain) would be the set of all y values greater than or equal to zero.
Thanks so much this helped me with my math assignment 🙏🙏🙏
Thank you so much for this video, took me wayyyyy too long to understand functions, but finally do! Appreciate it! :D
Glad it helped!

Thanks for taking the time to comment. I'm glad the video helped you to understand this concept, and I wish you well with your studies!
inspirational!!!!! Thank you very much
Well explained
Tq well explained tqqqqq so much
Searching this for long time atlast i found thankyou so much ❤ great job man
Glad I could help
i know this is late, but thank you so much! the way you explained it is very clear :)
Thanks ❤❤
Good work! Keep it up!!
Thank you!
Great explanation ...
Thank you! :-)
I'm lost. I'm still not understanding the difference between one to many and many to one
. It's literally the same thing
one to many is one input mapped on 2 or more outputs, many to one is inputs that has the same outputs (cmiiw)
love the videos
so do u call an input the domain and the output, the codomain
im just very confused😅
