a. Let $\displaystyle n=g(t)$ be the number of treatments (in millions) produced in the year that is *t* years since 2002. Find an equation of *g*.

My answer: $\displaystyle g(t)=5.5(2)^t$ ........ **OK**

b. What is the *n*-intercept of the model? What does it mean in this situation?

My answer: (0,5.5); In 2002, 5.5 million treatments of Tamiflu were produced. ........ **OK** It's the initial output.

c. Predict the number of treatments that will be produced in 2007.

My answer: $\displaystyle g(5)=176$. In 2007, 176 million treatments of Tamiflu will be produced. ........ **OK**

d. Roche plans to produce 300 million treatments in 2007. If that happens, will production continue to double each year from 2002 to 2007? Explain.

What would the answer be and why?
