How does the x-value of the vertex of a parabola relate to the x-intercepts?

• The x-value of the vertex is halfway between the x-intercepts.

• You can choose the x-value of the vertex and the x-intercepts.

• The x-value of the vertex is always closer to the smaller x-intercept.

• There is not a relationship between the x-value of the vertex and the x-intercepts.

• The x-value of the vertex is always closer to the larger x-intercept.
