 Question 288151: Tickets= -0.2x squared + 12x + 11 Does the graph open up or down and why. Describe what happens to the ticket sales as time passes. Use the quadratic equation to determine the last day that tickets will be sold. Will tickets peak or be at a low during the middle of the sale and why? After how many days will the peak or low occur? How many tickets will be sold on the day when the peak or low occurs? What is the point of the vertex? How many solutions are there to the equation and why. What do the solutions represent?
