Question

Help please. I do not really understand this practice question 

The graph depicted is a piecewise function with various segments, including linear and curved parts. It features points and segments of interest:

1. A cusp appears at \(x = -3\).
2. A gap or jump in the graph at \(x = 1\), indicated by an open circle at \((1, 2)\) and a closed circle at \((1, 4)\).

Task: 

- **Select all the points at which the graph is not differentiable:**

  - [ ] -4
  - [x] -3
  - [ ] -2
  - [ ] -1
  - [ ] 0
  - [x] 1
  - [ ] 2
  - [ ] 3
  - [ ] 4

The points where the graph is not differentiable are typically those with cusps, corners, or discontinuities.

Expert Solution
Check Mark
Step 1: concept

A function is non-differentiable when there is a corner point in its graph.


If the function is not continuous then it is not differentiable, i.e. when there is a gap or a jump in the graph of the function then it is not continuous hence not differentiable.
