Students in a mathematics class were given an exam and then tested monthly with an equivalent exam. The average scores for the class are given by the human memory model f(t)= 80-19 log10(t + 1), 0 ≤ t ≤ 12 where t is the time in months. Verify your answers in parts (a), (b), and (c) using a graphing utility. (a) What was the average score on the original exam (t = 0)? f(0) = (b) What was the average score after 2 months? (Round your answer to one decimal place.) f(2)= (c) What was the average score after 9 months? (Round your answer to one decimal place.) f(9) = Need Help? Read It
