You have a table that the average body mass index (BMI) among women of different ages in the United States in 2000. This question shows use of technology to summary: The data points in a chart?. Set all variables and all parameters clearly indicate what type of model behavior chart? to explain why he chose this role?
AGE BMI
2 16.40
3 15.70
4 15.30
5 15.20
6 15.21
7 15.40
8 15.80
9 16.30
10 16.80
11 17.50
12 18.18
13 18.70
14 19.36
15 19.88
16 20.40
17 20.85
18 21.22
19 21.60
20 21.65

I have the numbers in an Excel table (two columns).
Then, create a cloud of points (x, y)-values.
Finally, I have an order (polynomial trend line 3) and told him to show the function.
He came with this setting for a "better"
y = 0.0041x ^ 3 + 0.1536x ^ 2 - 1.2757x + 18,273
Choose a polynomial of 3rd OK, because I suspect there is a bath when they are younger, and maybe when I grow up, but I think it depends on a perfect model as a sin wave.
