Q26 of 64 Page 10

Choose the correct answer.

Let Then, f is


Given that


Checking the continuity at x = -1:


LHL at x =-1,



RHL at x =-1,



Hence, f(x) is continuous at x =-1.


Checking the differentiability at x =-1:


LHD at x =-1,




RHD at x =-1,




∵ LHD = RHD


Hence, options A and B are correct.
