f(x) decreasing on (1,3). f '(4) = 3(4)2 -12(4) + 9 = 9 positive . f(x) increasing on (3,). 4. Critical points: a) for which values of x (found above. in 3) is f(x) defined? x = 1 . and . x = 3. Note: The values of x found in steps 3a - 3c will always be in the domain of f(x) (and therefore defined). However, values of x found in step 3d may or ... ................
