Question
Studens in a psychology class took a final examination. As part of an experiment to see how much of the course content they remembered over time, they took equivalent forms of the exam in monthly intervals thereafer. The average score for the group f(t), after t months was modeled by this function: f (t) =81-15 In( t+1),0< and <12.What was the average score after 2 months. To find the average score after 2 months, evaluate the function:f(t) at t=2
f(2)=81-15 In (2+1) this is as far as I could go. Could I please get some help?
Explanation / Answer
f(2) = 81 - 15In(2+1)
f(2) = 81 - 15In(3) (now simply pull out a calculator and type the equation in)
f(2) = 64.52081567
