A. x = 0, crosses the x-axis;
x = 11, crosses the x-axis;
x = -11, crosses the x-axis
B. x = 0, touches the x-axis and turns around;
x = 11, crosses the x-axis;
x = -11, crosses the x-axis
C. x = 0, touches the x-axis and turns around;
x = 121, touches the x-axis and turns around
D. x = 0, touches the x-axis and turns around;
x = 121, crosses the x-axis

Solve the problem.The average waiting time in a line before getting served is given by ?W = 
where A is the average rate that people arrive at the line and S is the average service time. At a certain bank, the average service time is 4 minutes. By sketching a graph of the equation on the interval 
answer the following questions. What happens to W when A is close to zero? Why does this make sense? What feature of your graph gives this information?
