Question

list the points in the graph in the interval 0 < x < 7 at which the function is not differentiable. (use a comma to separate answers as needed.) the function is not differentiable at x =

Explanation:

Step1: Recall differentiability condition

A function is not differentiable at a point if there is a sharp - corner, cusp, vertical tangent, or discontinuity at that point in its graph.

Step2: Analyze the graph

In the given graph, check for points with the above - mentioned non - differentiable features in the interval \(0 < x<7\).

Step3: Identify non - differentiable points

We can see sharp - corners or cusps at \(x = 3\) and \(x = 6\).
