# Quadratics

### By: Jaida Ramirez

## Parabola

a symmetrical open plane curve formed by the intersection of a cone with a plane parallel to its side.

## Picture | ## Nothing! | ## Example If you kick a soccer ball (or shoot an arrow, fire a missile or throw a stone) it will arc up into the air and come down again |

## Quadratic

Involving the second and no higher power of an unknown quantity or variable

## Picture | ## Nothing! | ## Example If you throw a ball (or shoot an arrow, fire a missile or throw a stone) it will go up into the air, slowing down as it goes, then come down again |

## Vertex

1.) each angular point of a polygon, polyhedron, or other figure.

2.)

the highest point; the top or apex.

## Axis of symmetry

A line through a shape so that each side is a mirror image.

## Picture | ## Nothing! | ## Example If the shape were to be folded in half along the axis of symmetry, then the two halves would be the same, they would match up. |

## Maximum value

The largest value

## Minimum value

The smallest value

## Picture | ## Nothing! | ## ExampleA baseball is hit at a point 3 feet above the ground at a velocity of 100 feet per second and at an angle of 45 with respect to the ground. |

## Terms

letters and other general symbols are used to represent numbers and quantities in formulae and equations.

## First Differences

A Sequence is a set of things that are in order

## Second Differences

constant and equal to twice the number of n2 .

## Zeros(roots)

Where a function equals the value zero (0).
