Q119 / 180 · KCET 2015 · Mathematics

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
  • Correct answer
    D
    \( \mathrm{f} \) is not defined

Solution

Given that, $f(x)=\frac{1}{x} \rightarrow(1)$ When $x=0, f(x)=$ not defined Hence, $f(x)$ is not defined

Hence, the correct answer is option: 'D'.
