The scatterplot has 8 data points.
The data points are in a quadratic pattern opening downward.
The data points have the following approximate coordinates:
(9, 27)
(21, 29)
(29, 31)
(41, 35)
(49, 35)
(61, 32)
(71, 31)
(81, 30)

Which of the following equations is the most appropriate quadratic model for the data shown?

y = - 0.005 (x - 50)^{2} + 34

y = - 0.005 (x - 34)^{2} + 50

y = 0.005 (x - 50)^{2} + 34

y = - 0.005 (x - 34)^{2} - 50
