MCQ
$\mathop {\lim }\limits_{x \to 3} \,[x] = $, (where $[.] =$ greatest integer function)
  • A
    $2$
  • B
    $3$
  • Does not exist
  • D
    None of these

Answer

Correct option: C.
Does not exist
c
(c) $\mathop {\lim }\limits_{h \to {0^ + }} \,[3 + h] = 3$ and $\mathop {\lim }\limits_{h \to {0^ - }} \,[3 - h] = 2$

$\therefore$ $\mathop {\lim }\limits_{x \to 3} \,\,[x]$ does not exist.
