Expert Solution
Step 1

The following table shows the U.S gross domestic product in trillions of dollars as function of the year 't'

Advanced Math homework question answer, step 1, image 1

(a).

The meaning of G(2004) is the gross domestic product in the year 2004.

From the above table G(2004) = $ 11.87 trillion.

(b)

The functional notation to express the gross domestic in 2006 is G(2006)

The average increase from 2004 to 2006 is 

G(2006)=G(2004)+G(2008)2=11.87+14.372=26.242=13.12

So, the value of G(2006) = $13.12 trillion.
