MCQ
The solution of the function $f(x) = |x| > 0$ is:
  • A
    $R$
  • ✓
    $R – (0)$
  • C
    $R – (1)$
  • D
    $R – (-1)$
✓

Answer

Correct option: B.
$R – (0)$
Given, $f(x) = |x| > 0$
We know that modulus is non negative quantity.
So, $x \in R$ except that $x = 0$
$\Rightarrow\text{x}\in\text{R}-(0)$
This is the required solution
