Question

what is
the domain and range of function defined by f(x) = 4-x/x-4​

Answer 1

Answer:

F(x)=x-4/4-x find domain and range

Then at x=4 f(x) is not possible . So domain of f(x) is set of all real numbers except 4. Now range is the set of all y values possible . Thus range of f(x) is -1 as that is the only possible y value no matter what x is

Answer 2

Answer:

The range of the answer is -1 to +1
