Let C(t)C(t) be the cost of tuition at CBU in dollars for t years since 1990.
A quadratic model for the data is
C(t)C(t) = .
Use three decimals in your answer.
Estimate the tuition in 2016. $
Use the model to predict the year in which the tuition will be $15325.
The values of two functions, f and g, are given in a table. One, both, or neither of them may be exponential. Give the exponential models for those that are.
