If f(x) = ax^5 – 3x^2 + ax^2 – x, then f(b) – f(-b) will equal:	Choices.
A) 0  B) 2ab  C) 2ab^4 – 6  D) 2ab^5-2b  E) ab^5
f(x)=ax^5 – 3x^2 + ax^2 – x   f(b) = ab^5 – 3b^2 + ab^2 – b   f(-b) = -ab^5 – 3b^2 + ab^2 + b   f(b) - f(-b) = ab^5 – 3b^2 + ab^2 – b + ab^5 + 3b^2 - ab^2 – b   =2ab^5-2b   Answer 2ab^5-2b
