To find the y -coordinate of the vertex, we substitute x b 2a x b 2 a into the quadratic equation. The vertex is on the axis of symmetry, so its x -coordinate is b 2a b 2 a. “Private tutoring and its impact on students' academic achievement, formal schooling, and educational inequality in Korea.” Unpublished doctoral thesis. The axis of symmetry of a parabola is the line x b 2a x b 2 a.
