MCQ
The function $f(x)=|x|+\frac{|x|}{x}$ is
  • A
    Continuous at the origin
  • B
    Discontinuous at the origin because $|x|$ is discontinuous there
  • Discontinuous at the origin because $\frac{|x|}{x}$ is discontinuous there
  • D
    Discontinuous at the origin because both $|x|$ and $\frac{|x|}{x}$ are discontinuous there

Answer

Correct option: C.
Discontinuous at the origin because $\frac{|x|}{x}$ is discontinuous there
(C)
$|x|$ is continuous at $x=0$ and $\frac{|x|}{x}$ is discontinuous at $x=0$.
$\therefore f (x)=|x|+\frac{|x|}{x}$ is discontinuous at $x=0$.
