Different Types of Relations One to One Many to One and One to Many 

WOW! Thanks a Ton! I will make videos for you whenever you need. Feel free to post questions. Thanks Sudha!

No, it is on to many. Thanks

@@MathematicsTutor I think a circle is many to many. The a domain value x produces multiple y values and a range value y can be produced by multiple x values

I agree this video is incorrect I would not trust it also he says y=x^2 is a one to one when it is a one to many@@matthewjohnstone7324

Can you please elaborate. Did not understand the question. Thanks

the equations for the 4 relations@@MathematicsTutor

Thanks for appreciation

@@MathematicsTutor do you help me

How

Oh wait is it coz it’s a parabola ?

@@santanzotss yes

Yeah, that's true.

Not many to one, one to many. A horizontal parabola would be many to one!

He said 3, Lol! I think he don't know.

@@draculaoppa834 you shouldn't insult any one

@@satyanarayanaadapa49 I didn't even remember what I mean.

Highly appreciate that! It is difficult to get them on top of search engine. I really don't know how to do it. I don't even have a web-site to direct my viewers. I'm happy that some are able to appreciate! hope that many will join. Thanks for your thoughts!

Also watch my latest on Function: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-BDDzlFGwdrg.html

No. Relation is defined for the set of element. Even if one of them is related with many, it is not one-to-one Thanks

@@MathematicsTutor no sir, I meant suppose if a relation is one to many, can that relation btwn 2 sets have elements which also follow one to one relation?

Yes, it's a possibility that there can be some elements in the two sets that can have one to one relation but if we have even one relation of many to one or one to many then we don't call it a one to one relation.
