Question 308725: students in a class took a exam. as part of an experiment to see how much of the course they remembered. they took equivalent forms of the exam in monthly intervals. the average score for the group f(t), after T months was modeled by the function.
f(t)=88-12In (t + 1), 0
a) what was average score on original exam?
b) what was average score after 4 months?

You can put this solution on YOUR website! students in a class took a exam. as part of an experiment to see how much of the course they remembered. they took equivalent forms of the exam in monthly intervals. the average score for the group f(t), after T months was modeled by the function.
f(t)=88-12In (t + 1), 0
--------------------------------------
a) what was average score on original exam?
f(0) = 88-12*ln(1) = 88
=============================
b) what was average score after 4 months?
f(4) = 88-12*ln(5) = 68.69
============================
