While traveling across the country on a road trip, Hadassah passes the Indiana state line. Let d be the distance in miles of her car from the Indiana state line, and let t be the number of minutes since she passed the Indiana state line. The distance d is a function of the time t and is represented by the functionf, defined by d= f(t)= 0.0181² +1.07t What is the meaning of f(14)- f(9)? The change of distance of your car in the first 5 minutes after she passed the state line. The average speed of her car from t= 9 to t= 14 minutes.
