1.) Find the two zeros (roots), r and s, of the quadratic from the factored form. These value comes from the factored form y = a (x – r) (x – s). 2.) Take the average of r and s
The vertex formula is used to find the vertex of a parabola. There are two ways to find the vertex of a parabola. Vertex, (h, k) = (-b/2a, -D/4a) Where “D” is the discriminant where D = b2 – 4ac. “h” and “k” are the coordinates of the vertex.
To find equation of parabola from the given vertex and a point, we may use vertex form of the parabola. y = a (x - h) 2 + k Here (h, k) is the vertex. To find the value of a, we can apply the
use the (known) coordinates of the vertex, ( h, k), to write the parabola 's
