Question 627080: Tickets = -0.2x^2+12x+11
a. does the graph of this equation open up or down? how did you determine this?
b.describe what happens to the ticket sales as time passes?
c. use the equation to determine the last day that tickets will be sold?
d. will tickets peak or be at low during the middle of the sale? how do you know?
e.after how many days will the peak or low occur?
f. how many tickets will be sold on the day when the peak or low occurs?
g. what is the point of the vertex? how does this number relate to your answers in parts e and f?
h. how many solutions are there to the equation-0.2x^2+12x+11=0? how do you know?
i. what do the solutions represent? is there a solution that does not make sense? if so, in what ways does the solution not make sense?
