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.
(x = 1 is the day tickets go on sale).
Tickets = -0.6x2 + 12x + 11
Does the graph of the equation above open up or down?
Since the coefficient of x^2 is negative, it opens down.
Thank you Steve, your a life saver,and I appreciate your help!!!
To determine if the graph of the quadratic equation opens up or down, you need to look at the coefficient of the x^2 term. In this case, the coefficient is -0.6.
Since the coefficient is negative, the graph of the equation opens down.
