## How do quadratics relate to hitting a ball?

Quadratics shows the height and distance and time of the ball because it makes a curve in the graph. Its also a parabola so it curves. It could relate to hitting the ball because it shows how hard you hit the ball in the function and after that you could figure out the the height and distance at a certain point of time.

## -16t^2 + 100t

The time would be the independent variable while the height would be the dependent variable

## Domain and Range

Domain - All real's

Range - y≤156

## How long was the ball in the air?

The ball was in the air for 6.25 seconds

## At what time was the ball 65 feet in the air?

0.74 seconds and 5.51 seconds

## What effect would the change in elevation have on the graph?

It would make Earl's ball go higher and further and her ball will start at 20 ft above ground rather than at ground level

## Function describing new path

-16x^2 + 100x + 20

## Domain and Range

Domain- All reals

Range- y≤176.25
