A study analyzed the average yearly salt intake in the United States from 2012 thru 2017. The data is summarized in the table: Year Annual Salt Intake
(grams)
2012 3,435
2013 3,501
2014 3,560
2015 3,626
2016 3,690
2017 3,744

The study found that the data after the year 2012 can be modeled by the function f(x) = 59.4x + 3,429, 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 3,429.

O An estimate of the average grams of salt used in 2013

O An estimate of the average grams of salt used in 2012

O The average amount of salt in grams used in 2013

O The average amount of salt in grams used in 2012

Is an estimate of the average grams of salt used in 2012

Step-by-step explanation: Let

x ---> the number of years since 2012

f(x) ---> is the total amount of salt ingested in grams

we have

This is a linear equation in slope intercept form

where

The slope is equal to

The y-intercept or initial value is equal to

The y-intercept is the value of the function f(x) when the value of x is equal to zero

In this context, the y-intercept is the average amount of grams of salt ingested  in the year 2012

The exact value of the average amount of grams of salt ingested  in the year 2012 is 3,554 grams (see the data in the table)

Compare the exact value with the y-intercept

therefore

3,548 grams Is an estimate of the average grams of salt used in 2012
