In the vertex form, the (x,y) co-ordinates of the vertex is (h,k), and in the standard form the x-coordinate of the vertex is -b/2a and it's y.

It is possible to use three simultaneous equations to find the equation of each parabola in form \(\eqref{eq:1}\).However, this is a laborious approach and consequently there are plenty of opportunities for “silly” arithmetical errors!. The equation of a parabola is y = ax^2 + bx + c. With just two of the parabola's points, its vertex and one other, you can find a parabolic equation's vertex and standard forms and write the parabola algebraically.

This is indeed the case, and it is a useful idea. The vertex form of a quadratic is given by y = a(x – h) 2 + k, where (h, k) is the vertex. Y = ax 2 + bx + c In this exercise, we will be exploring parabolic graphs of the form y = ax 2 + bx + c, where a, b, and c are rational numbers.
