The following table shows total forest and timber land in the United States in millions of acres in the indicated year, calculus homework help

The following table shows total forest and timber land in the United States in millions of acres in the indicated year.

Year	1962	1970	1977	1987	1992
Timberland	759	754	737	731	737

A scatter plot of this data is shown below.

The horizontal variable is the number of years since 1962 and ranges between 0 and 30. Use quadratic regression to find a quadratic function to model the data. Enter your answer in the form y = ax^2+bx+c, where a, b, and c have been rounded to three decimal places. 
Important note: Do not include spaces in your answer and use the “^” symbol for exponentiation just as on the calculator.
