Air freshener A has a mass of 45 grams when opened and its mass decreases by 3.8 grams each day. Air freshener B has a mass of 45 grams when opened and its mass decreases by 3.8% each day. a. Write a function f that determines the mass of air freshener A (in grams) in terms of the number of days t since it was opened. f (t ) = Preview b. Write a function g that determines the mass of air freshener b (in grams) in terms of the number of days t since it was opened. g ( t ) = Preview c. Which of the following are true relative to this context? Select all that apply. (Hint: Consider graphing the functions f and g). O Air freshener A will eventually have a mass of 0 grams. It takes longer for air freshener A to reach a mass of 21 grams than air freshener B. 05 days after being opened, air freshener A will have a larger mass than air freshener B. O Air freshener B will eventually have a mass of 0 grams
