If $f : R \to R$ be defined by $f(x) = \frac{1}{x}, \forall x \in R$. Then, $f$ is
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → $f$ is not defined ##
Given that, $f(x) = \frac{1}{x}, \forall x \in R$
For $x = 0$, $f(x)$ is not defined.
Hence, $f(x)$ is a not defined function.
