**Property Tax Analysis in Massachusetts: 1997-2007**

Based on data from 298 of 351 cities and towns in Massachusetts, the average single-family property tax bill from 1997 through 2007 is approximated by the function:

\[ T(t) = 7.26t^2 + 91.7t + 2360 \qquad (0 \le t \le 10) \]

where \( T(t) \) is measured in dollars and \( t \) in years, with \( t = 0 \) corresponding to 1997.

### Questions

**(a) What was the average property tax on a single-family home in Massachusetts in 2001?**

\[ \text{Answer: } \$ \square \]

**(b) If the trend continued, what was the average property tax in 2008?**

\[ \text{Answer: } \$ \square \]

### Explanation

- The function \( T(t) \) represents the property tax amount in dollars as a function of time \( t \), with \( t = 0 \) indicating the starting year, 1997.
- The quadratic equation \( 7.26t^2 + 91.7t + 2360 \) includes:
  - A quadratic term \( 7.26t^2 \) which implies an accelerating increase in tax over time,
  - A linear term \( 91.7t \),
  - A constant term 2360 representing the initial property tax amount in 1997.

To solve the given questions:

1. Calculate the property tax in 2001 (\( t = 4 \)) by substituting \( t = 4 \) into the equation.
2. For the year 2008 (\( t = 11 \)), substitute \( t = 11 \) into the function to predict the tax, despite the function being explicitly given for \( 0 \le t \le 10 \).

Graphical or numerical approximations may be used for validation.
