Match the following

List - I	List - II
A) f : R → R is such that f (x) = px + q , (p ≠ 0) for all x ∊ R	I) f is neither one-one nor onto
B) f : R → R+ ∪ {0} is such that f (x) = x2 for all x ∊ R	II) f is both one-one and onto
C) f : N → N is such that f (n) = n2 + 2n + 3 for all n ∊ N	III) f is one-one but not onto
D) f : R → R is such that f (x) = 2 (cos25x+sin25x) for all x ∊ R	IV) f is onto but not one-one
	V) f is a constant function and also a bisection

The correct answer is
