Multiple Choice

Solve the problem.
-Let A=[132341253]A = \left[ \begin{array} { r r r } 1 & - 3 & 2 \\ - 3 & 4 & - 1 \\ 2 & - 5 & 3 \end{array} \right] and b=[244]\mathbf { b } = \left[ \begin{array} { r } 2 \\ 4 \\ - 4 \end{array} \right] .
Define a transformation T:R3R3\mathrm { T } : \mathfrak { R } ^ { 3 } \rightarrow \mathbb { R } ^ { 3 } by T(x) =Ax\mathrm { T } ( \mathrm { x } ) = \mathrm { Ax } .
If possible, find a vector x\mathbf { x } 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 } .
