Let \( f: R \rightarrow R \) be defined by \( f(x)=\frac{1}{x} \quad \forall \in R \), then \( f \) is
- A \( \) one-one
- B onto
- C bijective
- D \( \mathrm{f} \) is not defined
Answer & Solution
Correct Answer
(D) \( \mathrm{f} \) is not defined
Step-by-step Solution
Detailed explanation
Given that, \(f(x)=\frac{1}{x} \rightarrow(1)\)
When \(x=0, f(x)=\) not defined
Hence, \(f(x)\) is not defined
When \(x=0, f(x)=\) not defined
Hence, \(f(x)\) is not defined
