Modeling Data
21. The table shows that population y (in millions) of the United States for 2000 through 2005. The variable t represents time in years with t = 0 corresponding to 2000. |
t 0 1 2 3 4 5
y 282.4 285.3 288.2 291.1 293.9 296.6 a. Plot the data by hand and connect adjacent points with a line segment b. Use the slope of each line segment to determine the year when the population increased least rapidly |
