(Sensitivity Analysis for EOQB: x) in this problem, you will explore the EOQB model’s sensitivity to x, the fraction of demand that is backordered. a) Let Q(x) be the optimal Q for a given x. Derive and expression for g (Q(x), x), the cost that results from choosing an arbitrary value of x and then setting Q optimally. b) Prove that for any 0 = x = 1, c) Prove that if h
