Answer:
• Domain: The set of all real numbers from 0 to 60
,
• Range: The set of all real numbers from 300 to 420
Step-by-step explanation:
Given the function:
L = 2D + 300
Since the highest number of days the crew can work is 60, we have the highest Length of the road to be:
L = 2(6) + 320 = 420
The domain is the number of days the crew has worked, which is the set of all real numbers from 0 to 60
The range the length of the road in miles, which is the set of all real numbers from 300 to 420
