The data can be modeled by
in which f(x} and g(x) represent the average cost of roomand hoard at public four-year colleges in the school year endingx years after 201b. Use these functions: to solve Exercises 33-34.
Where necessary, round answers to the nearest whole dollar.
34. a. According to the linear node], what was the averagecost of loom and board al public four-year colleges for the school year ending in 2015?
b. According to the exponential model, what was theaverage cost of room and board at public four-yearcolleges for the school year ending in 2015? $7629
c. Which function is a better model for the data for theschool year ending in 2015? the $$$ model
The data in the following table indicate that between the ages ofI and 11, the human brain does not grow linearly, or steadily. Ascatter pint for the data is shown to the right of the table.
