SOLUTION: if {{{f(x)=1/sqrt(2x-4)}}} the domain of f(x) is?

Question 23090: if the domain of f(x) is?
Answer by stanbon!(97) (Show Source): You can put this solution on YOUR website!
Since 2x-4 cannot be zero or negative proceed as follows:
2x-4<=0
2x<=4
x<=2
These are the values the x cannot take.
So the domain is all real numbers that are not <=2.
Another way to say that is all real numbers that are >2.
