PassageBased on the above data, answer the given subquestions. Let T:R3→R3T:\mathbb{R}^3\to\mathbb{R}^3 be the linear transformation T(x,y,z)=(x+y+z,x−y−z,x)T(x,y,z)=(x+y+z,x-y-z,x).
QuestionIf A=[abc\def\ghi]A=\begin{bmatrix}a&b&c\d&e&f\g&h&i\end{bmatrix} denotes the matrix of TT with respect to {(1,1,1),(1,1,0),(1,0,0)}\{(1,1,1),(1,1,0),(1,0,0)\} for domain and codomain, what is 2b+2e+2h2b+2e+2h?
