**Title: Understanding Differentiability in Graphs**
**Task:**
Consider the graph of the function shown. Use the guidance on p. 143 to list all x-values at which the derivative of this function fails to exist. For each such x-value give the specific reason why the function is not differentiable.
**Graph Explanation:**
The graph provided is a plotted line graph, represented on a coordinate plane with x and y axes. Several critical points and features are visible:
1. **Points and Intervals:**
- The graph includes plotted points and line segments.
- There appears to be a discontinuity or sharp corner at some points.
- The line is continuous in sections but has breaks or jumps.
2. **Differentiability Issues:**
- At specific x-values, there might be points where the derivative does not exist, typically due to sharp corners, vertical tangents, or discontinuities.
3. **Observations:**
- Near the x-values 0, 2, and 3, consider areas where the function is not smooth.
- At these points, evaluate whether the graph has sharp turns or breaks, indicating non-differentiability.
**Analysis:**
This exercise will help you determine where a function lacks differentiability by analyzing sharp turns or discontinuities on its graph. Reflect on the graph's features, keeping in mind that a function is not differentiable at a point if it is not continuous there, if there is a sharp corner or cusp, or if there is a vertical tangent line at the point.
