# Math Vocabulary

## Parabola

A parabola is a U shaped line on a graph. They can be upwards or downwards and are created by having a squared variable on a graph.

A quadratic, or quadratic equation is an equation that has a squared variable. It can also create parabolas in charts and graphs. They usually have 4 parts in it's equation.

## Vertex

A vertex is the minimum point in a parabola on a graph.

## Axis of Symmetry

An Axis of Symmetry is An object that looks the same through axis rotation, which means that if you rotate the object, it will always look the same. It does not have to be symmetrical normally.

## Maximum Value

The Minimum value In a quadratic function is where “a” or a variable is less then 0. The maximum value is how high a positive parabola can go.

## Minimum Value

The Minimum value In a quadratic function is where “a” or a variable is greater than 0. The minimum value is how low a negative parabola can go.

## Terms

Terms are if either a single number or a variable, or numbers and variables multiplied together.

## First Differences

The First Differences are the y values in a set of data.

## Second Differences

The Second differences are the x values in a set of data.

## Zeros

The Zeros of a function is an input value that produces an output of zero (0). Where the variable equals zero. It is where the parabola crosses the x axis on both sides.
