You can put this solution on YOUR website!

you have f%28x%29=1%2F%28x-4%29
to have a real solution, you need to recall that denominator cannot be equal to zero
for x you can choose any value except the value which makes x-4=0 and that is x=4
so, domain is:
{ all x element of R: x%3C%3E4 }

in interval notation:
(-infinity,4) U (4,infinity)
