Please answer all parts to the first question and answer the same questions for the second question

Let f ( x ) = 3 x3 - 36 x + 3 Interval(s) on which f is increasing Interval (s) on which f is decreasing The point( s ) at which f achieves a local maximum The point ( S) at which f achieves a local mininum Intervals on which f is concave up Intervals on which fis concave down Find all inflection points Please find the same information for F (X) = 3x4- 6x2+ 9 I am using these two examples to study, Thank you
