Find the absolute maximum and absolute minimum values of the function $$f(x) = \left(x-1\right)\!\left(x-6\right)^{3}+4$$ on each of the indicated intervals.

(a) Interval = $[1, 4]$.

1.	Absolute maximum	=
2.	Absolute minimum	=

(b) Interval = $[1,8]$.

1.	Absolute maximum	=
2.	Absolute minimum	=

(c) Interval = $[4,9]$.

1.	Absolute maximum	=
2.	Absolute minimum	=
