Consider the following statements: I. f is an one-one function. II. f is onto function if the codomain is the set of natural numbers. Which of the statements given above is/are correct?
Options:
- a) I only
- b) II only
- c) Both I and II
- d) Neither I nor II Direction for Questions (109-110): Consider the following for the two (02) items that follow: Let the function f(x) = x2 – 1.

correct answer : a)
Explanation:
\ f(x) = px + q is linear polynomial so, f(x) is
one-one
Range = {1, 4, 7, 10}
codomain = N
So it is not onto.
\ f(x) = px + q is linear polynomial so, f(x) is
one-one
Range = {1, 4, 7, 10}
codomain = N
So it is not onto.
