10. The number of hours people in the United States spent playing video games each year from 1998 to
2001 can be modeled by the function   = 11.9 + 46.4 where x is the number of years since 1998.
a. Graph the function and identify it’s domain and range.
b. Find the value of   when  = 2. Explain what the solutions means in
this situation.
c. Find the value of   when  = 60. Explain what the solutions means in this situation.
11. A pool membership during the summer costs $7 per week. The total cost of membership is given by the
function   = 7. The pool also rents out lockers for $2 per week. The total cost of membership and a
rental is given by   = 9.
a. Graph both functions on the graph provided. How does the graph
of f compare to the graph of g.
b. What is the difference between a 12-week membership if you get
a locker and if you don’t? Explain how you got your answer.
