Find the number of all onto function from set A=(1,2,3,4,.........n) to itself
1 Answer

Dear Student,
As a rule we know number of onto function from a set to utself will be total permutation no of the no of elements.
Here the element no is n all all of them are different.
Therefore, total no of onto functions will definitely be n .
Cheers!!
