Neither of them Explanation: The graph of f is 2 424 2 4 6 On the other hand, after dierentiation, f ( x ) = 2 3 x 2 / 3 , f 00 ( x ) =4 9 x 5 / 3 . Consequently, A. has: ( f 00 ( x ) > , x < 0); B. not have: (see graph). keywords: horizontal tangent, concavity, True/alse, graph 010 (part 1 of 1) 10 points Which one of the following properties does f ( x ) = x4 x 2 + 20 have? 1. local min at x = 10 2. local min at x =10 3. local max at x = 10 correct 4. local max at x =10 5. local max at x = 2 6. local min at x = 2 Explanation:...
