And, the formula for the axis of symmetry is x=-b/2a. Vertex Form In vertex form, the quadratic equation is y=a (x-h)2 +k, given that (h, k) is the vertex of the given parabola. Lastly, the formula of ...

3. Analyze symmetry: Quadratic functions have an axis of symmetry that contains its vertex. This axis is a vertical line that passes through x = -b/2a (the same value for h in method one). By ...
