Anyway, I think that the answer to this question is A. I'm not sure, though.
Answer:
4
Step-by-step explanation:
because, if y = 4 and x = 1 then it would be 4/1 or 4 just simplify.
Y/X --- Y = 4 --- X = 1 ---- that makes 4/1 or 4

Step-by-step explanation:
Given

We have to find the difference of two functions given
So,
