<span>This question, in my opinion, is not well stated. If f(x) = √x, as the question statement seems to say, then the domain is not x<7. Rather, the domain is x≥0. If f(x) is not the square root function, but say f(x) = √(7-x) then the domain is x≤7, and for this function then the appropriate answer is d), since the x-term inside the radical has a negative coefficient.</span>

Answer:

D. $( {x} - 2)^{2} = 7$

Step-by-step explanation:

$3 {x}^{2} - 12x = 9 \\ 3( {x}^{2} - 4x) = 9 \\ {x}^{2} - 4 x= 3 \\ {x}^{2} - 4x + 4 = 3 + 4 \\ {x}^{2} - 4x + {2}^{2} = 7 \\ ( {x} - 2)^{2} = 7$
