list the points in the graph in the interval - 2 < x < 8 at which the function is not differentiable. the function is not differentiable at x = (use a comma to separate answers as needed.)
Answer
Explanation:
Step1: Recall non - differentiability conditions
A function is not differentiable at a point if there is a corner, cusp, vertical tangent, or discontinuity at that point.
Step2: Examine the graph
In the given graph, we look for such features in the interval (-2 < x<8). We can see that there are corners or sharp turns in the graph.
Answer:
2, 4, 6
