Answer:
Choice B. The vertex is (6,-4)
Step-by-step explanation:
Standard form of polynomial = ax² + bx + c
Zeros: x = {-2,3}
This gives the factors as, (x + 2) (x - 3)
On expanding this:
(x + 2) (x - 3)
x(x - 3) + 2(x - 3)
x² - 3x + 2x - 3
x² - x - 3
Polynomial = <em>x² - x - 3</em>
2/3 c = d
multiply both sides by 3/2:-
c = (3/2) d
