Question

log(x-4)<0 give domain

Answer 1

do you know the domain of f(x) = log(x) ?

Answer 2

First we need to make sure that x-4>0, that is, x>4.
Then log(x-4)<0 gives x-4<1, that is x<5.
So the domain is 4<x<5, or (4,5).

Answer 3

If you can remember the graph of f(x) = log(x)

it is easy to see the domain of log(x) is (0,∞)

Answer 4

note how the logarithm is not defined for negative x values
