Question

use the graph of the function f to find the value(s) of x at which f is not differentiable.
±2
-2
no correct answer choice is given.
0
2

Explanation:

Step1: Recall non - differentiability condition

A function is not differentiable at a point where there is a sharp corner.

Step2: Analyze the graph

The graph of the function $f(x)$ has a sharp corner at $x = 0$. At this point, the left - hand derivative and the right - hand derivative are not equal.

Answer:

0
