Tickets= -0.2x+12x+11

Does the graph of this eqution open up or down? How did you determine this

**Reiny**, Monday, April 13, 2009 at 10:00amyou probably meant to type:

Tickets= -0.2x^2 +12x+11 to have a quadratic

for any quadratic, if the coefficient of the x^2 term is negative, the graph opens downwards, if it is positive, then upwards.

Since your graph opens downwards, there has to be a maximum.

try x = 29, 30, and 31
