Text Solution
Verified by ExpertsThe correct answer is:
B
We have, 
. The domain of definition of 
is [–1, 1].
For 
we have
Since 
is not defined on the right side of 
and on the left side of 
. Also, 
when 
or 
. So, we check the differentiability at x = 0.
Now, (LHD at 
) = 
= 
= 
Similarly, (RHD at x = 0) = 
Hence, 
is not differentiable at x = 0.
