- Wait patiently for a helper to come along.
- Once someone helps you, say thank you and close the thread with: ```diff

here's a graph of f(x)
you can think of g as a moving vertical strip of width 1 that returns the max value in that strip
if the left edge is between -1 and 0, the max value is always at x = 0, in other words, 2
yess
as the left edge moves from 0 to 0.5, the max value then goes straight down to 1.5
then after that it starts increasing again, to infinity
yes yes then?
why did I do this out of order
as left edge goes from -infinity to -1.5, the max smoothly goes from infinity down to 1.5
then from -1.5 to -1, it goes up to 2
this is continuous clearly
so nondifferentiability is just when slope changes
yes
also you have to be a bit careful because the strip is defined in a weird way
g(x)'s left edge is x + 1
does that help?
well
I don't wanna just give the answer
