There can be two types of equations of a parabola which represent 4 different types of parabolas. The equation of any parabola involves a quadratic polynomial. 1. Top/Bottom opened parabolas are of the form y = ax2+ bx + c 2. Left/right opened parabolas are of the form x = ay2+ by + c Top/Bottom Opened Parabolas: The equation of a top/bottom opened...
When a parabola opens up or down, its equation in the standard form is of the form y = ax2 + bx + c. Here are the steps to find the vertex (h, k) of such parabolas. The steps are explained with an example where we will find the vertex of the parabola y = 2x2- 4x + 1. 1. Step - 1: Compare the equation of the parabola with the standard form y = ax2 +...
When a parabola opens left or right, its equation in the standard form is of the form x = ay2 + by + c. Here are the steps to find the vertex (h, k) of such parabolas which are explained with an example where we will find the vertex of the parabola x = 2y2- 4y + 1. 1. Step - 1: Compare the equation of the parabola with the standard form x = ay2 + b...
When a parabola opens to the left or right side, its equation in the intercept form is of the form x = a (y - p) (y - q), where (0, p) and (0, q) are the y-interceptsof the parabola. Here are the steps to find the vertex (h, k) of such parabolas. The steps are explained with an example where we will find the vertex of the parabola x = -(y + 3) (y -...

It is on the parabola's axis of symmetry. Illustrated definition of Vertex (parabola): Where a parabola makes its sharpest turn: the peak of the parabola.
Now another term that you'll see associated with the parabola, and once again, in the future, we'll learn how to calculate these things and find them precisely, is the vertex. The vertex you should view as the maximum or minimum point on a parabola.

Definition. A parabola is a curve where any point is at an equal distance from: a fixed point (the focus), and; a fixed straight line (the directrix)
