The average value formula in the interval (a,b) is

AV = 1/(b-a) * DEFINT f(x) {evaluated from a to b}
AV = 1/(b-a) * {INT f(4) - INT f(-4)}

The integral will be 1/2(x^4 - 5x^2). If you evaluate this at x=4 and then at x=-4 and do the math it will be 0.

So the answer is 0.

The average value is 1/8 integral of 2x^3-5x from -4 to 4

(1/2)x^4-(5/2)x^2

So it will be 0

average = [s(a+h)-s(a)]/h
[-4, 4] a=-4, (a+h) = 4 , h=8
f(x) = 2x^3 - 5x
{2(4)^3-5(4)-[(2(-4)^3-5(-4)]} / 8=27
@@...it's not on your answer list...
