## Parabola

A u-shaped curve with certain specific properties.

## Quadratic

An equation, graph, or data that can be modeled by a degree 2 polynomial.

## Vertex

The vertex of a parabola is the point where the parabola crosses its axis of symmetry.

## Axis of Symmetry

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

## Maximum Value

The maximum value of a quadratic function *f(x) = ax2 + bx + c *where *a*< 0,="" is="" the="">*y*- coordinate of the vertex.

## Minimum Value

The minimum value of a quadratic function *f(x) = ax2 + bx + c* where *a* > 0, is the *y*- coordinate of the vertex.

## Term

A Term is either a single number or a variable, or numbers and variables multiplied together.

## First Differences

The differences of the fist column of numbers.

## Second differences

The differences of the first difference.

## Roots

The points where the parabola crosses the x-axis
