If f(x) = ax^2 – 6x + ax + 1, then f(b) – f(-b) will equal: Choose the most appropriate option.
A) 0
B) -12b+2ab
C) 2ab^4 – 8b^2 – 6
D) -2ab^4 + 8b^2 + 6
E) 2ab^4 – 8b^2 + 2ab – 6
f(x)=ax^2 – 6x + ax + 1   f(b) = ab^2 – 6b + ab + 1   f(-b) = ab^2 + 6b - ab + 1   f(b) - f(-b) = ab^2 – 6b + ab + 1 - ab^2 - 6b + ab - 1   =-12b+2ab   Answer -12b+2ab
