Provide an appropriate response.
-xy = -9
A) A function with domain all real numbers except x = 0

Question

Quizplus · Accepted Answer

The equation xy = -9 has no restriction on the set of real numbers for x and y, except that it cannot have x = 0 because that would make y undefined. Therefore, the function has domain all real numbers except x = 0. The equation given only relates x and y, where y always equals -9. Therefore, x can take any value except 0, so its domain is all real numbers except x = 0. This statement is reflected in choice A. Choice B is not relevant to the given equation.
