Kai's Kites decided to advertise on billboards around town and track the relationship between the number of billboard advertisements they posted and the number of kites they sold. This table gives the total number of billboard advertisements they bought compared to the total number of kites they sold. The data can be modeled by a quadratic function.
Billboard advertisements	1	2	3	4	5	6
Kite sales	120	229	344	463	588	717
What function best models the data?

y equals 0.15 x squared minus 10.6 x plus 119
y=0.15x2+119
y equals 0.15 x squared plus 119
y=2.5x2+15.4x
y equals 2.5 x squared plus 15.4
y=2.5x2+102x+15.4
