Question

Find domain and range of mod x-4 ÷ x-4

Answer 1

Answer:

-1

Step-by-step explanation:

Domain is the set of all possible x values .

So x-4/4-x is only possible if 4-x is not equal to 0 .

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 simplifying f(x) we get,

x-4/(-1)(x-4)

= -1

Thus range of f(x) is -1 as that is the only possible y value no matter what x is .
