Question

Is the following relation a function?

X Y
6 ----> -1
-1 ----> 2
4 ----> 3
0 ----> 3

Yes or No (both 4 and 0 are pointing to 3)

Answer 1

Answer: Yes, it is definitely a function. Although one might say that it is not a one to one or injective function because of the presence of (-1,-2) and (6,-2).. The correct option among the two options that are given in the question is the second option. I hope that this is the answer that has actually come to your desired help

Answer 2

Yes, it is a function.
One-to-one mappings and many-to-one can both be classified as functions;
One-to-many mappings are the only kind that can't be classified as functions.
