Answer :
The domain and range of a function is the set of input and output values, the function can take.
- The domain is [0,6]
- The range is [0,90]
From the question, we have:
[tex]\mathbf{Rate = \$15}[/tex]
The domain
He cannot mow more than 6 yards a day.
This means that the domain is: 0 to 6
This is properly represented as: [0,6]
The range
When he mows 0 yards, his earnings is:
[tex]\mathbf{Earnings = 0 \times \$15 = \$ 0}[/tex]
When he mows 6 yards, his earnings is:
[tex]\mathbf{Earnings = 6 \times \$15 = \$ 90}[/tex]
This means that the range is: 0 to 90
This is properly represented as: [0,90]
