the graph of f is given. state the numbers at which f is not differentiable. (enter your answers as a comma - separated list.) enhanced feedback please try again. remember, functions are not differentiable at corners, discontinuities, or vertical tangents.

the graph of f is given. state the numbers at which f is not differentiable. (enter your answers as a comma - separated list.) enhanced feedback please try again. remember, functions are not differentiable at corners, discontinuities, or vertical tangents.

Answer

Explanation:

Step1: Identify non - differentiable points

Check for corners, discontinuities, vertical tangents.

Step2: Analyze the graph

At (x = 2), there is a corner. At (x=4), the graph has a vertical tangent.

Answer:

2,4
