I plotted the graph of the function and obtained:
The first column is the year number or x, the second column is the number of households.
1    7.96  1999
2    4.8    2000
3    3.2    2001
4    3.16  2002
5    4.68  2003
6    7.76  2004
a. During which years would the number of households be less than six million? 2000, 2001, 2002, 2003
b. In which year was the number of households participating at a minimum? I will answer 2002
