Question

A land scalpers mows lawns for at least 3 hours but not more than 6 hours the landscaper can mow 44,000 ft per hour the function f(t)=44,000 represents the number of sq feet the landscaper can mow in t hours what is the practical range of the function

Answer 1

It will be B because the numbers is functions

Explanation:

Answer 2

The practical range of the function is all real numbers from 132,000 to 264,000, inclusive

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
