(x = 1 is the day tickets go on sale).

Tickets = -0.6x2 + 12x + 11 .

Describe what happens to the ticket sales as time passes. My question is sinc the coefficient is negative and you graph downward the ticket sales would low? Please help

the number of ticket sales will increase until the maximum is reached, after that the ticket sales will decrease.

for any function

f(x) = ax^2 + bx + c, the max/min of the function is obtained when x = -b/(2a)

in your case

x = -12/(2(-.6)) = 10

when x = 10, tickets sales = -.6(100) + 12(10) + 11 = 71

I will leave it up to you to show that the sales are less for both x= 9 and x=11
