[x]
consider LHL n RHL
if x = 2 (for eg)
LHL be 1.99
[x] = 1
RHL = 2.01
[x] = 2
thus function is discontinous
hence the function is not differentiable

[x] is non differentiable only at Integer points. At all other points it's derivative is zero.
Its graph is like steps:

Derivative is basically slope
So it's 0 for non integral values and not defined for integral values
