Considere a aplicação linear \(T\) de \( \mathbb{R}^3 \) em \( \mathbb{R}^2 \) que transforma o cubo unitário \( C= x_1 \vec{e_1} + x_2 \vec{e_2} +x_3 \vec{e_3} : x_1,x_2,x_3 \in [0,1] \) na figura em baixo.Tendo em conta que \(T\) satisfaz \(T\left(\begin{array}{c}-7\\6\\5\\\end{array}\right)=\left(\begin{array}{c}0\\0\\\end{array}\right)\), qual dos seguintes vectores é \(T\left(\begin{array}{c}2\\1\\1\\\end{array}\right)\)?&lt;br /&gt;
