Parabolas


 * Hello everybody, this page can teach you every step and every short cut into doing parabolas. As I said, many people have learned parabolas along they way but eventually**, **everyone seems to be forgetting how or what parabolas are. However, this web page is dedicated into teach each and everyone of you how to work out the parabolas. In the video on the top of the page, it will show you an example of how to do a parabola.**

Parabola

Parabolas are used in graphs and in quadratic equations. A quadratic formula is y=x2 but there will also be other stuff added to it such as division and multiplication. Example: y=x2+3 ( A quadratic equation will always have x squared in its equation no matter what)


 * ~ TABLE ||~ GRAPH ||

x y -9 5 -8 -3 -7 -9 -6 -13 -5 -15 ||  || media type="youtube" key="XVt70aAYcUM" height="344" width="425"


 * Practice FOR PARABOLAS:

//1. x^2+4x-6-GRAPH THE FOLLOWING EQUATION

2. 2x+4x^2-9-GRAPH THE FOLLOWING EQUATION

3. 1.9x+2.97-8x^2-GRAPH THE FOLLOWING EQUATION

4. 2/3X^2-1/4-GRAPH THE FOLLOWING EQUATION//

FIND THE FOLLOWING EQUATION ON THE TABLE, THEN GRAPH IT **
 * ** x ** || ** y ** ||  ||
 * ** 1 ** || ** 4 ** ||
 * ** 2 ** || ** 16 ** ||  ||
 * **3** || **32** ||
 * **4** || **64** ||
 * **5** || **128** ||
