Answer:
D. All real numbers
Step-by-step explanation:
The range of a function is all of the possible x-values (which is easiest to understand if you can view a graph), and the domain of a function is all possible y-values.
So, you could put any x-value into this function (and it would have a corresponding y-value)
The domain [y] is limited, but the range [x] is best described as all real numbers
(if it's hard to remember which is which, d comes before r alphabetically, and x comes before y alphabetically)
Here is the answer from SparkNotes

Answer:
dy/dx = (cos y + y sin x) / (cos x + x sin y)
Step-by-step explanation:
y cos x = x cos y
y (-sin x) + dy/dx cos x = x (-sin y dy/dx) + cos y
-y sin x + dy/dx cos x = -x sin y dy/dx + cos y
dy/dx (cos x + x sin y) = cos y + y sin x
dy/dx = (cos y + y sin x) / (cos x + x sin y)
The answer is . (one [point] 4)
((Yes, its correct, checked and took an exam on it))
