I don't know where to begin for this problem.

What rules should I be looking to start this problem off?

You can get full credit for this problem by just answering the last question correctly. The initial questions are meant as hints towards the final answer and also allow you the opportunity to get partial credit. The integral

$\displaystyle \(\displaystyle \int_{-1}^{6}\left|12 x^2 - x^3 - 32 x\right|\, dx\)$ MUST be evaluated by breaking it up into a sum of three integrals:

$\displaystyle \[\int_{-1}^a\left|12 x^2 - x^3 - 32 x\right|\, dx +\] \[\int_a^c\left|12 x^2 - x^3 - 32 x\right|\, dx +\] \[\int_c^{6}\left|12 x^2 - x^3 - 32 x\right|\, dx\] $where

$\displaystyle a =$

$\displaystyle c =$

$\displaystyle \(\displaystyle \int_{-1}^a\left|12 x^2 - x^3 - 32 x\right|\, dx\) =$

$\displaystyle \(\displaystyle \int_a^c\left|12 x^2 - x^3 - 32 x\right|\, dx\) =$

$\displaystyle \(\displaystyle \int_c^{6}\left|12 x^2 - x^3 - 32 x\right|\, dx\)=$

Thus

$\displaystyle \(\displaystyle \int_{-1}^{6}\left|12 x^2 - x^3 - 32 x\right|\, dx\)=$

I'm not asking you to solve this for me, I just need to know where to start on this.
