Match the functions of List-I with their nature in List-II and choose the correct option. 
Then the correct match is
- A (a)
- B (b)
- C (c)
- D (d)
Answer & Solution
Correct Answer
(D) (d)
Step-by-step Solution
Detailed explanation
(A) \(f: R \rightarrow R\) \[ f(x)=\cos (112 x-37) \] \(f(x)\) is periodic function. \(\therefore\) It is not injective. Range of \(f(x)\) is \([-1,1]\) \(\therefore\) It is also not surjective. \(\therefore \quad \mathrm{A} \rightarrow \mathrm{IV}\) (B)…
