Question

Consider the function represented by graph (c). How many times would the derivative of this function change signs? never once twice three times can not be determined Consider the function represented by graph (a). Which of the following statements describe this function? Its derivative changes sign once Its second derivative changes sign twice For x INFINITY Its derivative is negative at x = 0 All of the above None of the above (Assume that the figure above represents the graphs of f(x) , f '(x), and f "(x). Using your answers to the previous questions as a guide, identify which function (f(x), f '(x), or f ··(x» corresponds to each graph (a, b or c) in each of the following. Graph (a) represents: f(x) f '(x) f OO\"(x) Not enough information to determine Graph (b) represents: f(x) f '(x) f ··(x) Not enough information to determine Graph (c) represents: f(x) f ·(x) f "(x) Not enough information to determine

Explanation / Answer

Graph B is the first derivative of A, and Graph C is the second derivative of A. 1) c 2) d 3) d 4) a 5)b 7)c
