For the graph of the function, identify the axis of symmetry, vertex and the formula for the function. Axis of symmetry: x = –0.5; Vertex: (, –0.75); f(x) = x2 – x + 1 Axis of symmetry: x =; Vertex: (, 0.75); f(x) = x2 + x + 1 Axis of symmetry: x = –0.5; Vertex: (, 0.75); f(x) = x2 + 2x + 1 Axis of symmetry: x = –0.5; Vertex: (, 0.75); f(x) = –x2 + x
