# Real World Parabola

### Austin Sanford and Tate Trueblood

## Picture taken at Austin's house

## Vertex

(7,0)

## Two other points

(8,5) and (8,0)

## Equations

Standard Form: y=-4x^2+bx+7

Vertex Form: y=-a(x-4)^2+7

## What does the height of the parabola represent?

The distance from the concrete to the top of the brick.

## At the spot where the brick touches the ground what is the relevance to the equation?

It is where the parabola crosses the x axis.

## What is the maximum Height?

The maximum height is 7 feet.

## How far away is the ground from the maximum height?

10 feet from the start of the parabola to the vertex.

## What is the domain?

-4 is less than or equal to x and x is greater than or equal 4

## What is the range?

0 is less than or equal to y and 7 is greater than or equal to y.
