Piecewise Defined Functions, Modeling, Domain/Range 1. Factory in Wichita A) The cost of producing 25,000 units is $1. From 25,001 units to 35,000 units the cost lowers to $0.80. B) f(x)= {$1, for 1 x 25,000 $0.80, for 25,000, x 35,000 C) The cost is $0.80 D) The company should calculate the marginal cost and make adjustments E) ___ The plant’s production processes are performed primarily by robots that are able to work longer hours, when needed, at no additional cost. 2. Factory in Seattle A) B) When x = 8000 The cost remains constant at 0.35 when x increases from 0 to 8000 The slope of cost function over this part is 0. When 8000 x = 20000 The cost remains constant at 0.75 when x increases from 8000 to 20000 The slope of cost function over this part is 0. When 20000 x = 42000 The cost decreases when x increases from 20000 to 42000 The slope of cost function 3. Factory in Omaha A) The rate of decrease is 0.00001 dollars per unit B) The function will then be y = -0.00001x + 0.97 C) The cost per unit at the production level of 19,000 is 0.78 dollars 4. Analysis and Making Production Decisions A) Wichita: $1 Seattle: $0.75 B) We will send the order to the Seattle factory since they have the lowest cost per unit. B2) Combination A Wichita: 7,000 units = $1 Seattle: 30,000 units = $0.68
