Which of the formulas below could be a polynomial with all of the following properties: its only zeros are $x= -8, -2, 2$, it has $y$-intercept $y = 6$, and its long-run behavior is $y \to -\infty$ as $x \to \pm \infty$? Select every formula that has all of these properties.

A. $y=- \frac{6}{64} (x + 8)(x + 2)(x-2)^2$

B. $y=-6 x(x + 8)(x + 2)(x-2)$

C. $y=- \frac{6}{256} (x - 8)(x - 2)(x+2)$

D. $y=- \frac{6}{64} (x + 8)(x + 2)^2(x-2)$

E. $y=\frac{6}{64} (x + 8)(x + 2)(x-2)^2$

F. $y=- \frac{6}{256} (x + 8)(x + 2)^4(x-2)$

G. $y=- \frac{6}{256} (x + 8)^2(x + 2)(x-2)$
