For the graph of the function, identify the axis of symmetry, vertex and the formula for the function.
A. Axis of symmetry: x = β1; Vertex: (β1, 0); f(x) = βx2 β 2x β 1
B. Axis of symmetry: x = β1; Vertex: (β1, 0); f(x) = β2x2 β 2x β 1
C. Axis of symmetry: x = β1; Vertex: (β1, β1); f(x) = βx2 β 2x β 1
D. Axis of symmetry: x = β1; Vertex: (β1, 0); f(x) = βx2 β x + 2
