Answer 1

Let the transformation matrix be denoted by A:

$A = \begin{bmatrix} 1 & 0 & 1 \\ 1 & 1 & 0 \\ 0 & 1 & -1 \end{bmatrix}$

The transformation T is defined as:

$T(\begin{bmatrix} a \\ b \\ c \end{bmatrix}) = A \begin{bmatrix} a \\ b \\ c \end{bmatrix}$

We are given two examples:

1. $T(\begin{bmatrix} 1 \\ 0 \\ 1 \end{bmatrix}) = \begin{bmatrix} 1 \\ 1 \\ 0 \end{bmatrix}$ Let's verify this:

$\begin{bmatrix} 1 & 0 & 1 \\ 1 & 1 & 0 \\ 0 & 1 & -1 \end{bmatrix} \begin{bmatrix} 1 \\ 0 \\ 1 \end{bmatrix} = \begin{bmatrix} 1(1) + 0(0) + 1(1) \\ 1(1) + 1(0) + 0(1) \\ 0(1) + 1(0) + (-1)(1) \end{bmatrix} = \begin{bmatrix} 2 \\ 1 \\ -1 \end{bmatrix}$

This contradicts the given information. There's an error in the problem statement. The result should be $\begin{bmatrix} 2 \\ 1 \\ -1 \end{bmatrix}$, not $\begin{bmatrix} 1 \\ 1 \\ 0 \end{bmatrix}$.

2. $T(\begin{bmatrix} 1 \\ 1 \\ 1 \end{bmatrix}) = \begin{bmatrix} 2 \\ 1 \\ -1 \end{bmatrix}$ Let's verify this:

$\begin{bmatrix} 1 & 0 & 1 \\ 1 & 1 & 0 \\ 0 & 1 & -1 \end{bmatrix} \begin{bmatrix} 1 \\ 1 \\ 1 \end{bmatrix} = \begin{bmatrix} 1(1) + 0(1) + 1(1) \\ 1(1) + 1(1) + 0(1) \\ 0(1) + 1(1) + (-1)(1) \end{bmatrix} = \begin{bmatrix} 2 \\ 2 \\ 0 \end{bmatrix}$

This also contradicts the given information. The result should be $\begin{bmatrix} 2 \\ 2 \\ 0 \end{bmatrix}$, not $\begin{bmatrix} 2 \\ 1 \\ -1 \end{bmatrix}$.

Conclusion:

The problem statement contains errors in the given transformations. The provided matrix A and the given transformations do not match. To correctly determine $T(\begin{bmatrix} a \\ b \\ c \end{bmatrix})$, we need accurate information about the transformation's effect on at least three linearly independent vectors. With the current, contradictory information, a correct solution cannot be provided.
