A The range is the set of all real numbers less than 0.

• Incorrect, positive values only

B The domain is the set of all real numbers greater than-4.

• Incorrect, the domain can get any value

C The range is the set of all real numbers greater than 0.

• Correct, the range is restricted to positive values

D The domain is the set of all real numbers less than-4.
