In the graph of function given below mention the x values where the function fails to be differentiable, and also mention the reason why it fails to be differentiable. Hint: There is nothing wrong with the point x = 10

From the provided graph, I will analyze the differentiability of the function at key points. Differentiability fails where the graph shows any sharp turns (cusps or corners), discontinuities, or vertical tangents.

### Points where the function fails to be differentiable:
1. **x = -10**:
   - The graph has a sharp cusp here, meaning that the slope of the tangent line changes abruptly. The function is continuous but not differentiable because the derivative (slope) from the left is different from the right.
   
2. **x = -4**:
   - There is a jump discontinuity at \( x = -4 \). The graph breaks and moves directly to a different value. At points of discontinuity, the function is not continuous, so it cannot be differentiable.
   
3. **x = 0**:
   - Another sharp corner (cusp) appears at \( x = 0 \), similar to \( x = -10 \), where the slope from either side of the point is different, causing the function to fail to be differentiable.
   
4. **x = 8**:
   - There's a cusp at \( x = 8 \), where the graph turns sharply. The tangent slopes on either side are not equal, indicating the function is not differentiable here.

### Key Point: \( x = 10 \)
- The graph at \( x = 10 \) does not show any issues with continuity or sharp turns, so there is no problem with differentiability at this point.

### Conclusion
The function fails to be differentiable at:
- \( x = -10 \)
- \( x = -4 \)
- \( x = 0 \)
- \( x = 8 \)

### Tip:
For a function to be differentiable at a point, it must be both continuous and smooth at that point, meaning no sharp corners, cusps, or discontinuities.

Analyze the graph to identify points where a function is not differentiable. Explore sharp corners, cusps, and discontinuities as reasons for non-differentiability. Suitable for Grades 10-12.
