for two The region of experimentation factors are temperature (Levels of T set to: 100,200 and 300 °F) and catalyst feed rate (Levels of C set to: 10,20 and 30 lb/h). A first order model in the usual coded variables has been fit to a molecular weight response, yielding the following model y = 2000+ 1.5 x1 - 0.8 x2. Assume that the change in the most relevant coded variable is equal to one. The overall objective is maximizing the response. Which is the steepest ascent change for natural Variable T?
