Question

Find domain and range if, f(x)= 4-x/x-4

Answer 1

Answer:

domain is R-{4}

range is R

Step-by-step explanation:

Answer 2

Answer:

The function is not defined at x = 4

So the domain of the function is R - {4}

Now for x#4

f(x)= 4-x/x-4 = - (x-4) / x-4 = - 1

So the range of the function = { - 1}
