# Quadratics in Golfing!

### By: Brett Coleman and Anand Singh

## Question 1-4

function: f(t)=-16t^2+100t

f(t)= height of the golf ball

t= time elapsed

The independent variable in this situation is the amount of time that has passed by and the dependent variable is the amount of feet the ball is in the air.

Domain: 0 __<__ x __<__ 6.25

Range: 0 __<__ X __< __156.25

The x axis title from the graph to left is time (S.) and the y axis title is the distance (ft.) in air.

The ball was in the air for 6.25 seconds

## Question 7.1 The ball's height is 154 feet after 3.5 seconds. | ## 7.2 There is another time where the ball was at a height of 154 feet because this equation creates a parabola. It is also 154 feet at 2.75 seconds. |

## Question 9

Tweety Bird will be increasing 4 feet per second. The equation would be y=4x meaning that this is a linear function. Tweety Bird will be the same height as my ball after six seconds. The height of the ball will be 24 seconds.

The x axis title from the graph to left is time (S.) and the y axis title is the distance (ft.) in air.
