Question
Is the given relation a function? Give reasons for your answe $r:s = (n, n^{2 }) | n$ is a positive integer
✓
Answer
We have$, s = (n, n^2) |$ n is a positive integer
Since the square of any positive integer is unique$,$ every element in the domain has unique image. Hence$, S$ is a function.
