Answer: A
Step-by-step explanation: Domain means the x values. Since Miguel works between 15 and 25 hours, the appropriate x values (independent variable) are between 15 and 25.
B is wrong because between 100 and 300 would be the range (y values). C is wrong because a specific domain (between 15 and 25) is specified in the problem, and all real numbers would also include negatives, which isn’t realistic for this scenario. D is wrong because a specific domain is specified. Therefore, it couldn’t be all numbers greater than 0.
