The graph below shows the graph of f (x), its derivative f "(x), and its second derivative f "(x). which of the following is the correct statement?
a graph is shown with three functions. function a is a parabola with a minimum of about 0 comma negative 8 crossing the y axis around x equals negative 0.8 and around x equals 0.8. function b is a quartic function with 2 minimums around x equals negative 1.5 and x equals 1.5 and one maximum at x equals 0. function c is a cubic function increasing to a local maximum at about negative 0.8 comma 4.25 then decreasing through an inflection point at the origin and then increasing around 0.8 comma negative 4.25 to the right.
a. a is f ', b is f, c is f ".
b. a is f ", b is f, c is f '.
c. a is f ', b is f ". c is f.
d. a is f, b is f ', c is f ".
