1. **(a)** Write the function for the linear model that gives the number of North American business email users in millions, where \( x \) is the number of years since 2005, with data from \( 0 \leq x \leq 5 \). (Round all numerical values to three decimal places.)

   \( m(x) = \) ___________________ million users

2. **(b)** What is the constant rate of change of the number of North American business email users? (Round your answer to three decimal places.)

   ___________________ million users per year

3. **(c)** Use the model to estimate the number of North American business email users in 2017. (Round your answer to three decimal places.)

   ___________________ million users

4. Is this estimate found by interpolation or extrapolation?
   - [ ] interpolation
   - [ ] extrapolation
