Hey, could someone please help me get started on this problem, I'm not sure how to go about it. Thanks heaps. Where is the function h(x) = |x - 1| + |x + 2| differentiable? (a) Give a formula for h'(x). (b) Sketch the graphs of h and h'

Where is the function h(x) = |x - 1| + |x + 2| differentiable? (a) Give a formula for h'(x). (b) Sketch the graphs of h and h' The function will be differentiable everywhere except the cusps. Where are these?
I think at x = 1 and x = -2. Do I have to split the function to find h'(x)?
Yes on both counts
