The axis of symmetry and the x-coordinate of the vertex are represented by the same formula. Which formula is correct?

• Axis of symmetry: x = 1, x-coordinate of the vertex: 1
• Axis of symmetry: x = 2, x-coordinate of the vertex: 2
• Axis of symmetry: x = 0, x-coordinate of the vertex: 0
• Axis of symmetry: x = -1, x-coordinate of the vertex: -1

The general form of a parabolic function

• y = ax² + bx

• y = ax² + c

• y = ax² + bx + c

• y = ax² + bx + d

• Axis of symmetry: x = 1/3, X-coordinate of the vertex: 1/3
• Axis of symmetry: x = 2/3, X-coordinate of the vertex: 2/3
• Axis of symmetry: x = -1/3, X-coordinate of the vertex: -1/3
• Axis of symmetry: x = 1, X-coordinate of the vertex: 1
