[@tanveerbhat3306]

very nice explanation

[@Styla-es7dk]

Agr set A main koi akela reh jaye to kya wo one to one function kehlaiye ga?

[@sqnldrmirwais]

If in a set \( X \), one element is not related to any element in set \( Y \), then the relation between \( X \) and \( Y \) cannot be a function. In a function, each element in the domain (set \( X \)) must be related to exactly one element in the codomain (set \( Y \)). If there exists an element in \( X \) that is not related to any element in \( Y \), then the relation does not satisfy this requirement of a function.
In other words, for every element \( x \) in \( X \), there must be exactly one element \( y \) in \( Y \) such that \( (x, y) \) is in the function. If there's an \( x \) that does not have any corresponding \( y \), it violates the definition of a function.
So, the type of relation you described would not be a function. It could be a relation, but it wouldn't meet the criteria for a function.

[@AAA-k8h7h]

The function will simply not exist

[@TheUP93Rider.]

​@@sqnldrmirwais simple bolo function will not exist

[@topoholicbeatthetop9300]

Function hi nhi rhega woh then

[@radhika2232]

[@ThirumalaKandadi]

TQ sir

[@GajrajBisht-g5s]

Agr koi fx one one h to wo onto bhi hoga kya ?

[@kritikavishwakarma9293]

Onto can be one-one and vice versa but not necessary it depends on the defined relation

[@strikeout7371]

Sir doubt hai 😭. One one function me ek domain ka ek hi image hoga Aisa aapne bataya. But ek yt. Channel hai dear sir karke unke video me to kuch or bataya gya hai 😢
