The effectiveness of studying for an exam depends on how many hours a student studies. For a certain exam, a student is given one day to study. Some experiments show that if the effectiveness E, is put on a scale of 0 to 6, then E(t)-(2), where t is the number of hours spent studying for the exam. How many hours should a student study to achieve maximum effectiveness? 15.43 hours 14.43 hours 16.43 hours None of the above
