Given information
Given a non differentiable function.
Step-by-step explanation
Step 1.
There are three ways in which a function can be differentiable:
(a) Corner
In general, if the graph of a function 
has a “corner” or “kink” in it (or if the curve of the graph is not smooth and has a sharp point ), then the graph of has no tangent at this point and is not differentiable there.
