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: (-0.5, 0.75): f()=x2 + x
O Axis of symmetry: x=-0.5: Vertex: (-0.5, 0.75): f(x) = x2 +x+1
O Axis of symmetry: x=-0.5; Vertex: (-0.5, -0.75): f(x) = x²-x+1
O Axis of symmetry: x=-0.5: Vertex: (-0.5.0.75): f(x) = x2 + 2x + 1
