If f(x) represent the percent of American homes with computers and g(x) represent the number of American homes, with x equal to the number of years after 1990.

AWhat function represents the number of American homes with computers, with x equal to the number of years after 1990?
BWrite the number of American homes with computers in 2015 using this function notation.

Verified Answer :

AThe number of American homes with computers after 1990 can be calculated by multiplying the number of American homes, g(x) with the percentage, f(x). The function is therefore,
                                    (g(x))(f(x)
b. There are 25 years between 1990 and 2015. So, the equation becomes,
                                    (g(25)(f(25))
