Let than number of points of non diffrentiability of f(x) equals
1
2
3
4
As we have learned
Properties of differentiable functions -
Absolute functions are always continuous throughout but not differentiable at their critical point.
-
will be non diffrentiable at x=1, so overall non diffrentiable at x=1
will be non diffrentiable at x=2, so overall non diffrentiable at x=2
No. of required points =2
