Answer:
The correct option is (C).
Step-by-step explanation:
We need to find the correct option that does not represent y as a function of x.
In options A, B, D and E, both x and y are involved. It means we can represent y as a fucntion of x.
But in option (c), it has only y as a variable i.e.
-4y=-8
y=(8/4)
y = 2
So, this option does not represent y as a function of x.
