Here: The Body mass Index (BMI) is a measure of the proportion of fat in the body of the individual. This index is calculated by dividing weight (in kilograms) of the individual by the square of height (in meters).

The table below gives the median BMI of girls according to their age in the United States in 2000;

Age(year): 2/3/4/5/6/7/8/9/10/11/12/13/14/15/16/17/18/19/20

1. By using a calculator or computer, place a mark describing these items donated. Set all variables used and clearly specify any parameter.

2. What types of functions used to model the behavior of this curve? Explain why you have such functions. Create yourself a function (an appropriate model for these points

Explain clearly your approach.
