Types Of Parabolas Math
The parabola is therefore symmetrical about x axis which is the axis of symmetry of parabola.
Types of parabolas math. 2 y 2 4ax for a 0 x may have negative value or zero but no positive value. Y 2 4ax a left handed parabola. Y 2 4ax an up facing parabola. Different types of parabolas.
There are different types of equations in which we get a parabola. As discussed earlier there are four standard forms of a parabola. The point midway between the focus and the directrix on the parabola is called the vertex. In short they represent.
If the x axis and the y axis are interchanged then the focus is at the point f 0 a and the directrix is the line having the equation y a. Horizontal parabola that opens to the right y y 0 2 4p x x 0 x x 0 p 0. The vertex of the parabola is the origin. We see that for the equation y 2 4 a x the parabola opens to the right if a 0 and to the left if a 0.
1 y 2 4ax for a 0. Therefore in this case the parabola opens to left. The standard form of these equations with vertex as origin are. A right handed parabola.
One description of a parabola involves a point the focus and a line the directrix the focus does not lie on the directrix. X 2 4ay a down facing parabola.
