<PRE><B>Question 1206304</B>
&lt;br&gt;
The quadratic term in all 4 answer choices is x^2, which means the equation in standard form has a=1.  Because of that, the given information that the graph passes through (2,-8) is not needed.&lt;br&gt;
Solution method 1...&lt;br&gt;
If the roots are 3 and -6, then the linear factors are (x-3) and (x-(-6))=(x+6).  The equation is then y = (x-3)(x+6) = x^2+3x-18.&lt;br&gt;
ANSWER: C&lt;br&gt;
Solution method 2...&lt;br&gt;
With a=1 in the standard form, Vieta&#39;s Theorem says the sum of the roots is -b and the product of the roots is c.&lt;br&gt;
The sum of the roots is 3+(-6) = -3, so b is 3; the product of the roots is 3(-6) = -18, so c is -18:  y = x^2+3x-18.&lt;br&gt;
ANSWER: C&lt;br&gt;
