Dints (3, 2) and (7, 2) are on the graphs of both quadratic functions f and g. The graph of f pens downward, and the graph of g opens upward. Which of these statements are true?
I. The graphs of f and g have the same axis of symmetry.
II. The graphs of f and g have the same * -intercepts.
III. The graph of f has a maximum point, and the graph of g has a minimum point.
IV. The graph of f is the result of a reflection of the graph of g across the x -axis.
