QuestionExample 5.2.1. Let T(x1,x2,x3)=(x1x2,2x1+2x2+x3,x1+x2+x3)T\left(x_{1}, x_{2}, x_{3}\right)=\left(x_{1}-x_{2},-2 x_{1}+2 x_{2}+x_{3},-x_{1}+x_{2}+x_{3}\right) and b=(1,0,1)\vec{b}=(1,0,-1). Determine whether bT(R3)\vec{b} \in T\left(\mathbb{R}^{3}\right).

Studdy Solution
Since there's no solution to the system, the vector (1,0,1)(1, 0, -1) is *not* in the range of the transformation TT.
So, bT(R3)\vec{b} \notin T(\mathbb{R}^3).
