# Quadratics!!!

### Brooke Sherrell

## Parabola

a symmetrical open plane curve formed by the intersection of a cone with a plane parallel to its side. The path of a projectile under the influence of gravity ideally follows a curve of this shape.

## Quadratic

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

## Vertex

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

## Axis of symmetry

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

## terms

In Algebra a term is either a single number, a variable, or numbers and variables multiplied together.

## first differences

The differences between y-values of a function for evenly spread x-values.

## second differences

Differences between first differences of a function.

## zeros

Any number x such that f(x)=0
