Respuesta :
The numbers at which f is not differentiable are; -1, and 2
The reason the above list of numbers at which f is not differentiable are correct are given as follows:
Question; Please find attached a graph that can be used to solve the question
- A function is not differentiable at a point where the function has a discontinuity. That is a point on the graph were there is a break in the graph
Therefore, the given graph of f shows that the function is not differentiable at x = -1, the point where the graph has a discontinuity
- A function is not differentiable at a point where the graph of the function has a kink or corner.
The graph of f has a kink at x = 2, therefore, the function is also not differentiable at x = 2
