Let V = \(\mathbb{R}^3\) and let B = {(1, 0, 1), (1, 1, 1), (0, 0, 1)} and B' = {(1,0,1), (0,1,0), (-1,0,0)}\n two bases for V.\n(1) Find the transition matrix P from B' to B.\n(2) Let T a linear operator on V with \([T]_B = \begin{pmatrix} 1 & -1 & 1 \\ 0 & 1 & 1 \\ -1 & 2 & 0 \end{pmatrix}. Find \([T]_{B'}.\n(3) Is T an isomorphism?
