The graph of the function y = x2x2 is shown below.
Which of the following shows the correct key features of the graph?
A)vertex (1/2, -21/4), axis of symmetry x=1/2 intercepts at (-1, 0) and (2, 0), y-intercept at (-2, 0).
B)vertex(1/2, -2 1/4), axis of symmetry x =-2 1/4, x-intercepts at (-1, 0) and (-2, 0), y-intercept at (0, 2).
C)vertex (1/2, -2 1/4), axis of symmetry x = -2 1/4, x-intercepts at (-1, 0) and (2, 0), y -intercept at (0, -2).
D)vertex (1/2, -2 1/4), axis of symmetry x=1/2, x-intercepts at (-1, 0) and (2, 0), y -intercept at (0, -2).
