For the graph of the function, identify the axis of symmetry, vertex and the formula for the function. A. Axis of symmetry: x = 0.5; vertex: (-0.5, 0.5); f(x) = -2x^2 + 2x - 1

B. Axis of symmetry: x = -0.5; vertex: (-0.5, -0.5); f(x) = -2x^2 - 2x - 1

C. Axis of symmetry: x = 0.5; vertex (0.5, -0.5); f(x) 2x^2 - 2x - 1

D. Axis of symmetry: -0.5; vertex: (-0.5, -0.5); f(x) = -2x^2 + 2x - 1
