Homework Statement
∫ |x^2 -9| [0-4]
Homework Equations
The book answer states the same EXCEPT splits into [0-3] and [3-4]. Other problems split the integral perfectly in half for absolute values...why would it differ and are there rules to figure this out? Larson's Calculus has no mention...sigh...
The Attempt at a Solution
I split the expression into |9x-x^3/3| [0-2] and |x^3/3 - 9x| [2-4] and get -45/3
Book answer 64/3
