Well, |x| is differentiable everywhere except x = 0.
Thus, the only points in question are x = 1 and x = 3.

Oh so even at x=3?

Oh so even at x=3?
Well, spoiler: x = 3 is fine. But you still need to make sure 😁

It's (x-3)^3

Unless you prove a more general result, of course.

Mhmmm

What about this one? Haha

Oh, sorry, didn't notice your solution.
Yeah, that works.
