Question

In 1997, the average tuition at four-year public universities was $2,360 per year. In 1998, that figure rose to $2,430 per year.
a) If tuition increased linearly, write a formula for the tuition as a function of years since 1997. Use your function to estimate the tuition in 2006.

b) If tuition increased exponentially, write a formula for the tuition as a function of years since 1997. Use your function to estimate the tuition in 2006. Note: The average tuition in 2006 was actually $4,102.
