If f(x)={sin⁡(1+[x])[x]for [x]≠00for [x]=0f(x)=\left\{\begin{array}{cl}\frac{\sin (1+[x])}{[x]} & \text {for }[x] \neq 0 \\ 0 & \text {for }[x]=0\end{array}\right. where [x][x] denotes the greatest integer ≤x\leq x, then lim⁡x→0−f(x)\lim \limits_{{x \rightarrow 0-}} f(x) equals
View answer and explanation
Correct option: B
0
The correct answer is B (0) because as x approaches 0 from the left, the greatest integer function [x] equals -1, and the limit is calculated accordingly.
