## To state:The number of points where given graph of function f is not differentiable.

Expert Solution

The numbers are 2 and -1 where f is not differentiable.

### Explanation of Solution

Given: The graph of function.

Let f be any function and graph of this function is given.

It has to find numbers of points at which f is not differentiable.

The function f is not differentiable at the following numbers:

x=2 Because the two sides of the curve meet at that point so f is not differentiable at that point.

x=1 Because the graph of f is jump here.

Hence, the numbers are 2 and -1 where f is not differentiable.
