The vertex of a parabola is the turning point (a.k.a. the maximum or minimum)
The axis of symmetry of a parabola is a vertical line that passes through the vertex/turning point of the parabola, and that divides the parabola into two congruent halves.
The x-coordinate of the vertex is the equation of the axis of symmetry (x = __ )
