Tom Turkey has been concerned about his weight gain as Thanksgiving approaches. He started measuring his weight about six weeks before the holiday and found that it followed a pattern modeled as: W(t) = - 25 +3 + 0.5 (t +5)2 +0.75 where t represent the number of weeks he has been tracking his weight gain and W represents the weight gain in ounces. What was his average weight gain between the second and the fourth week he was measuring? What was the instantaneous weight gain at the second week? What was the instantaneous weight gain at the fourth week? Do you think Tom is worried about who is being served at Thanksgiving dinner?
