Answer:
The domain is all real values greater than or equal to 0 seconds and less than or equal to 40 seconds
The range is all real values greater than or equal to 0 feet and less than or equal to 2,000 feet
Step-by-step explanation:
Let
t ----> is the amount of time since the descent began
f(t) ---> is the height of a hot-air balloon descends
we know that
The linear equation in slope intercept form is equal to
where
m is the unit rate or slope of the linear equation
b is the y-intercept or initial value
In this problem we have that
The slope or unit rate is equal to
---> is negative because is a decreasing function
The y-intercept or initial value is equal to
substitute
The domain is the interval -----> [0,40]
All real values greater than or equal to 0 seconds and less than or equal to 40 seconds
The range is the interval ----> [0,2,000]
All real values greater than or equal to 0 feet and less than or equal to 2,000 feet
