Multiple Choice

Solve the problem.
-Let A=[130402412]\mathrm { A } = \left[ \begin{array} { r r r } 1 & - 3 & 0 \\ - 4 & 0 & 2 \\ 4 & 1 & - 2 \end{array} \right] and b=[964]\mathbf { b } = \left[ \begin{array} { r } 9 \\ - 6 \\ 4 \end{array} \right] .
Define a transformation T\mathrm { T } : R3R3\mathfrak { R } ^ { 3 } \rightarrow \mathbb { R } ^ { 3 } by T(x) =Ax\mathrm { T } ( \mathbf { x } ) = \mathrm { Ax } .
If possible, find a vector xx whose image under T\mathrm { T } is b\mathbf { b } . Otherwise, state that b\mathbf { b } is not in the range of the transformation T\mathrm { T } .


A)
[320]\left[ \begin{array} { r } 3 \\- 2 \\0\end{array} \right]
B) b\mathbf { b } is not in the range of the transformation TT .
