Here is my problem. Students in an acct class took a final exam and then took equivalent forms of the exam at monthly interval there after. the average score S(t), as a percent, after t months was found to be given by the function S(t)= 78 -15 log(t+1), t>-0.
1.What was the ave test score when students initially took the test, t=0?
2.what was the ave test score after 4 mths, and 24 mths?
also graph the given functions and explain the normal characteristics (domain, range, x intercept, y intercept, and asymptotes).
