Vertex of a Horizontal Parabola
The vertex of a horizontal parabola is the point where the curve intersects its axis of symmetry. For the standard form equation , the vertex is the point . For the general form equation , the -coordinate of the vertex is found by using the axis of symmetry formula , and the -coordinate is calculated by substituting this -value back into the original equation to solve for .
