3-3a #3

Consider the function $\"f(x)$ . For this function there are three important intervals: $\"(-\\infty,$ , $\"[A,B]\"$ , and $\"[B,\\infty)\"$ where $\"A\"$ and $\"B\"$ are the critical numbers.
Find $\"A\"$
and $\"B\"$
For each of the following intervals, tell whether $\"f(x)\"$ is increasing (type in INC) or decreasing (type in DEC).
$\"(-\\infty,$ :
$\"[A,B]\"$ :
$\"[B,\\infty)\"$ :

f\'(x) = -6x^2 + 66x - 168 = (x-7)(x-4) A = 4, B=7 inc, dec, inc
