1. The problem statement, all variables and given/known data
Find the Local and absolute extrema of f(x) on the interval [-1,2] and give a sketch of the graph if:
f(x) = [ 1 / (1 + |x|) ] + [ 1 / (1 + |x - 1|) ]
I am confused about the absolute value parts. I know they're the versions inside the absolute value signs when >0 and the negative of the inside when < 0 but I'm not sure how to start this derivative.
Help would be appreciated. Thanks.
