The total revenue from the sale of a popular book is approximated by the rational function $$R ( x ) = \frac { 1700 x ^ { 2 } } { x ^ { 2 } + 4 }$$ , where $$x$$ is the number of years since publication and $$R ( x )$$

is the total revenue in millions of dollars.

(a) Find the total revenue at the end of the first year.

(b) Find the total revenue at the end of the second year.

R(x)=$$\frac{1700x^{2} }{x^{2}+ 4 }$$
when x=1 then R(x)=$$\frac{1700}{5}$$=$340 million when x=2 then R(x)=$$\frac{1700\times4 }{8}$$=$850 million
