Please solve RD Sharma class 12 Chapter Functions exercise 2.1 question 5 sub question (xvi) maths textbook solution.
Neither injective nor surjective.
Injective (one-one): function means every element in the domain has a distinct image in the co-domain.
Surjective(Onto): function means every element in the co-domain has at least one pre image in the domain of function.
Let x,y be any two elements in domain R such that
Therefore, f is not an injection.
Let y be any two elements in domain (R) such that for some element x in R.
So, f is not a surjection and f is not a bijection.
