I asked differentiability
It is not differentiable at x=1. Fractional part is not differentiable at x=1.
Please tell LHD and rhd in the solution they are 3 for both but I am getting LHD 1 and rhd 3
Yes you are solving it right @ruchi it will be RHD=3 and LHD=1 only.
Sorry for the confusion. Didn't read [x].
