From the function, the correct interpretations are:
1. 55% of U.S. households had internet use in 2003.
2. k% of U.S. households had internet use in 1984.
3. At least 61% of U.S. households had Internet use in 2007.
4. The sum of the percents of U.S households with Internet use in 1997 and 2001 is the same as the percent of U.S households with Internet use in 2009.
---------------------------
The function H(x) represents the percentage of households with Internet in x years after 1980, thus x is the number of years after 1980 and H(x) is the percentage of households with internet in year 1980 + x.
1. H(23)=55
- 1980 + 23 = 2003, thus 55% of U.S. households had internet use in 2003.
2. H(4)=k
- 1980 + 4 = 1984, thus k% of U.S. households had internet use in 1984.
3. H(27)≥61
- 1980 + 27 = 2007, thus: At least 61% of U.S. households had Internet use in 2007.
4. H(17)+H(21)≈H(29)
- Following the same logic as previous items, as considering that the output is a percentage: The sum of the percents of U.S households with Internet use in 1997 and 2001 is the same as the percent of U.S households with Internet use in 2009.
