y = [-1 1] .* sqrt( x - 2 );
This is maths rather than Matlab though. Once you rearrange the equation the Matlab code for it is trivial!
There are numerous ways to code it and if you don't care about the negative root then it is even more trivial.

You probably need the Symbolic Math Toolbox for that then, although it isn't something I do in my work so there may be methods in base Matlab too.
