If the absolute maximum value of the function $$f(x) = (x^2 - 2x + 7)e^{(4x^3 - 12x^2 - 180x + 31)}$$ in the interval $$[-3, 0]$$ is $$f(\alpha)$$, then
Given,
$$f(x)=(x^2-2x+7)e^{(4x^3-12x^2-180x+31)}$$
on the interval
$$[-3,0]$$
Let
$$g(x)=x^2-2x+7$$
and
$$h(x)=4x^3-12x^2-180x+31$$
Then,
$$f(x)=g(x)e^{h(x)}$$
Differentiate:
$$f'(x)=e^{h(x)}\left[g'(x)+g(x)h'(x)\right]$$
Now,
$$g'(x)=2x-2$$
and
$$h'(x)=12x^2-24x-180$$
$$=12(x-5)(x+3)$$
Therefore,
$$f'(x)=e^{h(x)}\left[(2x-2)+(x^2-2x+7)(12x^2-24x-180)\right]$$
Since
$$e^{h(x)}>0,$$
critical points come from
$$g'(x)+g(x)h'(x)=0$$
Now check important points in
$$[-3,0]$$
At
$$x=-3,$$
$$h(-3)=4(-27)-12(9)-180(-3)+31$$
$$=-108-108+540+31$$
$$=355$$
and
$$g(-3)=9+6+7=22$$
Hence,
$$f(-3)=22e^{355}$$
At
$$x=0,$$
$$h(0)=31$$
and
$$g(0)=7$$
Thus,
$$f(0)=7e^{31}$$
Clearly,
$$22e^{355}\gg7e^{31}$$
Also,
$$h'(x)=12(x-5)(x+3)<0$$
for
$$-3<x<0$$
Hence exponential part decreases throughout the interval, making
$$f(x)$$
strictly decreasing on
$$[-3,0]$$
Therefore, absolute maximum occurs at
$$x=-3$$
Hence,
$$\boxed{\alpha=-3}$$
