Owen has enough materials to build up to 10 birdhouses in shop class. Each birdhouse needs 12 square feet of wood. The function W(b) = 12b represents the total amount of wood that Owen would need to build b birdhouses. What domain and range are reasonable for the function?
A. D: 10 ≤ b ≤ 12 R: 0 ≤ W(b) ≤ 120
B. D: 0 ≤ b ≤ 10 R: 0 ≤ W(b) ≤ 120
C. D: 0 ≤ b ≤ 120 R: 0 ≤ W(b) ≤ 10
D. D: 0 ≤ b ≤ 10 R: 12 ≤ W(b) ≤ 120

Each birdhouse uses 12 sq ft of wood.
He has enough to build 10 birdhouses, so he has 120 sq ft of wood.
The function has an input of the number of birdhouses, b, and has an output of the amount of wood needed, W. b is the input or the domain, and W is the output or the range. The domain is 0 to 10. The range is 0 to 120.

Answer:  B. D: 0 ≤ b ≤ 10 R: 0 ≤ W(b) ≤ 120
