The table gives the U.S. population, in millions, for selected years from 1950 and projected to 2050.

(a) Create a scatter plot for the data in the table. Use x as the number of years past 1950.
(b) Use the scatter plot to identify and determine at least two function types that could be used to model these data.
(c) Which model more accurately approximates the data point for the year 2040?
(d) Use the linear model to determine when the U.S. population is predicted to reach 425 million.
