a. The 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))
