The solution is,

However, when I tried finding the domain myself:

## { x | x - 1 ≥ \sqrt{5}} ## (Sorry, for some reason the brackets are not here)

##{ x | x - 1 ≥ -\sqrt{5}} ## and ## { x | x - 1 ≥ \sqrt{5}}##

##{x | x ≥ 1 -\sqrt{5} }## and ## { x | x ≥ \sqrt{5} + 1}##

However, I don't understand how ##x ≥ 1 -\sqrt{5}## and ##x ≥ \sqrt{5} + 1## can both be true. Because of that, I also don't understand how they got the domain.

Many thanks!
