Question

A function can be classified as one to one correspondence, one to many correspondence and many to one correspondence.

#sorryimidiot:( please help me

Answer 1

A function can be classified as :—

1) ONE TO ONE IF ALL ELEMENTS OF X SET HAVE ONE DIFFERENT Y VALUE. NO TWO CAN HAVE SAME VALUE.

EG:- X —» 2,3,1

Y —» 4,6,2

Y = 2X IS A ONE TO ONE FUNCTION

2) MANY TO ONE IF ATLEAST ONE Y VALUE HAS TWO X VALUES FOR IT.

EG:- X—» 4,-4

Y—» 16

Y = X² IS A MANY TO ONE FUNCTION

3) ONE TO MANY

I BELIEVE IT'S IN THE DEFINITION OF FUNCTION THAT IT CAN'T BE OF ONE TO MANY TYPE

Hope It Helps
