Answer:
The practical range of the function is all real numbers from 132,000 to 264,000, inclusive
Step-by-step explanation:
The range of a function is the complete set of all f(t).
f(t) = 44,000t
which represent the number of sq feet the landscaper can mow in t hours
t must be at least 3 hours but not more than 6. Mathematically:
3 ≤ t ≤ 6
These correspond to the following function values:
f(3) = 44,000*3 = 132,000 ft²
f(6) = 44,000*6 = 264,000 ft²
Then:
132,000 ≤ f(t) ≤ 264,000
