Question

help please! “find all points (x) where the function g(x)= |x+2| - |x-8| is not differentiable….”

Answer 1

A function is not differentiable at a point if the function has a "sharp/angled point''.

The solution will be resolved with the graph shown below

From the graph,

$g(x)\text{ }is\text{ not differentiable at x =}-2,8$
