Answer
Explanation:
Step1: Recall non - differentiability conditions
A function is not differentiable at a point if there is a sharp corner, a cusp, a vertical tangent, or a discontinuity at that point.
Step2: Analyze the graph
- At (x=-4), the graph has a sharp corner. So the function is not differentiable at (x = - 4).
- At (x = 2), there is a hole (a removable discontinuity). The function is not differentiable at (x=2) since the function is not continuous at (x = 2).
Answer:
-4, 2
