If f(x) = ax^3 + x^2 + ax – 2x, then f(b) – f(-b) will equal: Choose the correct choice from the following options
A) 2ab^3 - 2ab  B) 2ab  C) 2ab^3 + 2ab - 4b  D) - 4b  E) 2ab^3
f(x)=ax^3 + x^2 + ax – 2x   f(b) = ab^3 + b^2 + ab – 2b   f(-b) = - ab^3 + b^2 - ab + 2b   f(b) - f(-b) = ab^3 + b^2 + ab – 2b + ab^3 - b^2 + ab – 2b   =2ab^3 + 2ab - 4b   Answer 2ab^3 + 2ab - 4b
