Find the absolute maximum and absolute minimum values of the function

(x^3)+(12x^2)-27x+9

on each of the following interval

[-10,0]

3. The attempt at a solution

I got this and its saying its wrong.

y'= (3x^2)+(24x)-27

factor: 3(x^2+8x-9) so x=-9 and x=-1

y''=6x+24

I plug in -9 into there and come up with -30 as the minimum which is not correct?

Anyone have some input?

Thanks! Dan
