From the graph of the parabola, determine whether the parabola opens upward or downward, and find the vertex, axis of symmetry, and range of the function. Find the maximum or minimum value of the function and the intervals on which the function is increasing or decreasing.
A. Down, (3, 9), x = 3, (-?, 9], max 9, inc (0, 9], dec (-?, 0]
B. Down, (3, 9), x = 9, [3, ?), max 9, inc (-?, 3], dec [3, ?)
C. Down, (3, 9), x = 9, [9, ?), max 9, inc (-?, 3], dec [3, ?)
D. Down, (3, 9), x = 3, (-?, 9], max 9, inc (-?, 3], dec [3, ?)
