Question

The linear model represents the height, f(x), of a water balloon thrown off the roof of a building over time, x, measured in seconds:

-During what intervals of the domain is the water balloon's height increasing?
-During what intervals of the domain is the water balloon's height staying the same?

Answer 1

Answer:

1) (0-2)sec  2) (2-4) sec and (10-14)sec

Step-by-step explanation:

1) Since the graph has a positive slope during time interval 0-2 sec ..the height of the balloon was increasing during this time

2) sine the slope is 0 from time interval (2-4) and (10-14)

the height of the balloon remains same during these time

Hope you got your answer

:)

Answer 2

Answer:

Step-by-step explanation:

a. 0-2 seconds as the slope goes up

b. 2-4 seconds as it is stable and a straight line

c. 4-6 as from 6 to 8 it decreases by 20ft and the same for 8 to 10 but it decreases by over 20ft and almost 40ft during 4-6 seconds
