Marks: +1, -0

Given that for any n∊N there exist on odd integer q and a non- negative integer r such that, n can be written uniquely as n=q×2r.
Let f:N→N×N be function defined by f(n)=(r+1,

q+1

). Then,

f is one-one but not onto
f is onto but not one -one
f is a bijection
only f−1(1,1) does not exist because f is not a bijection
