f(x) = 3x^2


f(-3) = 3(-3)^2


f(-3) = 3(9)


f(-3) = 27


f(x) = 3x^2


f(3) = 3(3)^2


f(3) = 3(9)


f(3) = 27


-------------------------------------------------------------------------


Average Rate of Change = (f(b) - f(a))/(b-a)


Average Rate of Change = (f(3) - f(-3))/(3-(-3))


Average Rate of Change = (27-27)/(3-(-3))


Average Rate of Change = (27-27)/(3+3)


Average Rate of Change = 0/6


Average Rate of Change = 0


So the final answer is 0
