Question 593803: Suppose you are an event coordinator for a large performance theater. One of the hottest new Broadway musicals has started to tour and your city is the first stop on the tour. You need to supply information about projected ticket sales to the box office manager. The box office manager uses this information to anticipate staffing needs until the tickets sell out. You provide the manager with a quadratic equation that models the expected number of ticket sales for each day x. ( is the day tickets go on sale).

Does the graph of this equation open up or down? How did you determine this?

Will tickets peak or be at a low during the middle of the sale? How do you know?
Rachel�s Tips: In other words, will there be a max (peak) or min (low) in this situation?
Your Solution - Show your Work Below
After how many days will the peak or low occur?
Rachel�s Tips: Since # days = x in our situation, find the x-value of the max/min (vertex).
