[tex]f(g(x))=f(\sqrt{x-2})[/tex]
[tex]f(g(x))=3(\sqrt{x-2})^{2}+4[/tex]
[tex]f(g(x))=3(x-2)+4[/tex]
[tex]f(g(x))=3x-6+4[/tex]
[tex]f(g(x))=3x-2[/tex]

The second answer is correct.
Square g(x), multiply by 3, 3x-6+4 = 3x-2.
The domain depends on the square root term which must have its argument greater or equal to zero.
Therefore x-2 >= 0, so x>=2
