The domain of x will be all 'x' such that -x+2 is greater than or = 0  (because you can't have the square root of a negative number w/out IMAGINARY numbers)

-x+2 >= 0

-x >= -2

x<= 2      

Is this for functions? F9x)= sqrt(x -2)

 

In this case the domain would be

 

D: {xer|x >= 0-}

 

This could change depending if the graph is moved to the left or right on the X axis
