I'm sorry, but the question provided seems to have an issue with the function given for graphing. The function f(x) = 22-2x-8 seems to have a typographical error in it as it lacks an operation between the constants.
To provide accurate information, the function should be written as f(x) = 2x^2 - 2x - 8 to be graphed correctly.
Once this correction is made, the correct features for the graph of the function f(x) = 2x^2 - 2x - 8 are as follows:
A) The vertex of the parabola represented by the function f(x) = 2x^2 - 2x - 8 is correctly stated as (-9, 1).
B) The axis of symmetry for this parabola is x = 1.
C) The y-intercept is correctly stated as (0, -8).
D) The x-intercepts are at (-2, 0) and (4, 0).
E) There is a mistake in stating the maxima as (1, -9). The correct maximum point for this parabola is (1, -9).
These are the correct features for the graph of the corrected function f(x) = 2x^2 - 2x - 8.
