Golfing Project

By Brett D. and Ben W.

Question 1

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
