Root of y is possibly iff y is 0 or positive number, so that is only for numbers bigger or equal than c. This is still surjective on that codomain, but that don't covers all of real numbers.
The main aim of the channel was to provide tutorials for each topic since most of the other channels solve just random problems. As we started with fe let's finish them first! 😉
I like your proof of injectivity.
Bro I am from India loved ur Videos and preparing for Indian National Mathematical Olympiad (Inmo)Plz keep uploading videos
I’m looking forward to your next video!
Awesome as always
Hi what books you suggest to prepare for imo? Am at 9th grade and I want to get medal at imo
I think it would be better if you do a longer video ,spend more time on the topic being taught in near future
What if we substitute P(0,root of y)?Can we get surjectivity?like f(f(root of y)^2)=f(0)+y=c+y

Please recommend me a book on combinatorics for national Olympiads.🙏

@@littlefermat from what i have heard it's a advanced level book, can you please suggest something for a beginner level ??
Last video?
Not yet!
In the next video we'll deal with a rational functional equation.

I see someone is starting to wear a hat. I wonder who is also wearing a hat some of the time... :P :D
Easy
I think he is more comfortable with functional equations, as his most of the videos are of that

@@littlefermat yess broo I feel the same way 😐... Thats why i have joined your channel ❤️❤️
