1. 6.9 Modeling With Polynomial Functions

2. Polynomial Modeling With Technology
The table shows data on the increase in girth of a tee in a redwood forest over a 10-week period.
Week
Increase (mm)
0.34 2
0.35 4
0.37 6
0.31 8
0.18 10

3. Polynomial Modeling With Technology
Find a quartic model for the data.
Use the model you found in part (a) to estimate the increase in girth in week 5.
In which week was the increase in girt about 0.25 mm?
