I thought it was [-2,-1) U (-1, 0) U (0,1) U (1,3] U [4,5]
but apparently thats not the right answer and I dont know where i'm going wrong

anonymous · Answer

it is not differentiable at -2  so that interval should be open

anonymous · Answer

not differentiable at 3 either because of the corner

anonymous · Answer

make your intervals open and i don't see 5 on it $(3,4)$ for the last one

anonymous · Answer

wow I dont know how I didnt see that... Thank you!!! Apparently I needed an extra set of eyes :p
