# Golfing Project

On graph.

## Question 2

Independent = Time in seconds

Dependent = Height in feet

## Question 3

0 ≤ Domain ≤ 6.25

0 ≤ Range ≤ 156.25

## Question 4

6.25 seconds ## Question 5

156.25 feet is the maximum height. It is 156.25 ft because that is that is the y value when the x value of 3.125 is plugged into the equation y = -16 (x^2) + 100x. The x value of 3.125 was obtained after using the formula, - b / 2a. ## Question 6

3.125 seconds to reach the maximum height. 3.125 was calculated after using the

formula, - b / 2a. ## Question 7

The ball is at the height of 154 feet after 3.5 seconds and also 2.75 seconds.  ## Question 8

I think the time for the ball to reach 65 feet is approximately .7 seconds. based off of looking at my graph. Also, I think it would also be 5.5 seconds for the ball to reach 65 feet too when descending.  ## Question 9

It took the bird 6 seconds to fly to the height of 24 ft. where it will be at the same height as the ball. ## Question 10

Gloria's ball hit the ground first by 1.25 seconds and her ball will reach a maximum height of 100 ft.  ## Question 11a

If Earl hit the ball 20 ft above ground, then on the graph, it would raise the y-intercept by 20.

## Question 11b

It would look like f(t) = -16t^2 + 100t + 20.

## Question 11c

0 ≤ domain ≤ 6.444

20 ≤ range ≤ 176,25
