A forest fire has been burning for several days. The burned area, in acres, is given by the equation y = (4,800) . 2, where d is the number of days since
the area of the fire was first measured a b. d = -1 corresponds to 1 day before the area of the fire was first measured, and d = -3 corresponds to 3 days before. b b. d = -1 corresponds to 3 day before the area of the fire was first measured, and d = -3 corresponds to 1 days before. c b. d = -1 corresponds to 2 day before the area of the fire was first measured, and d = -3 corresponds to 6 days before. d b. d = -1 corresponds to 7 day before the area of the fire was first measured, and d = -3 corresponds to 10 days before.
