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
Inspect the graph for points with sharp turns, vertical tangents, or breaks. There is a sharp corner at (x = - 2) and a discontinuity at (x=2).
