A study analyzed the average yearly salt intake in the United States from 2012 thru 2017. The data is summarized in the table: Annual salt intake
Year
(orams)
2012 3618
2013/3,646
2014 3.680
2018 3.716
2016 3.751
2017 3.790
The study found that the data after the year 2012 can be modeled by the function f(x) = 36.4x + 3,608, where x is the number of years since 2012 and f(x)
is the total amount of salt ingested in grams. Describe the significance of 3,608
