Axia College Material Appendix F Ticket Sales Living in or near a metropolitan area has some advantages. Entertainment opportunities are almost endless in a major city. Events occur almost every night, from sporting events to the symphony. Tickets to these events are not available long and can often be modeled by quadratic equations. Application Practice Answer the following questions. Use Equation Editor to write mathematical expressions and equations.

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). a. Does the graph of this equation open up or down? How did you determine this? Since “a” or the coefficient of the x squared term is negative (-.2), this graph will open downwards. b. Describe what happens to the tickets sales as time passes. A regular parabola which opens down always increases in both the x and y values as time passes, then at one point the graph reaches a point at the largest y value, and then as time passes on the x value increases more but the y values start to decrease. Same occurs here, so the when the days go on the ticket sales increase, and at one
