Consider the following graph 5'} a) At which point. is the second derivative greater. b or d. and why? '0] Reproduce a sketch of this curve and indicate where the cum: is concave up and where it is concave down, the points where the ' ' at c) What must be true about the second denvatwe verso? Give a clear curve changes concavity from up to dOWn. or vice- justjcation for your answer. (1) What must be true about the second derivative near the right-hand end of the graph, and why? 9) Put. all this together to sketch the graph of the second derivative 0f \"119 function. Label the points a through d on your sketch
