\lim_{d \to 2^-} f(x) = 2

d! = 2

f(x)=x\,\!


T_o \begin{bmatrix} x \\ y \end{bmatrix} = \begin{bmatrix} -8 \\ -11 \end{bmatrix} T_o \begin{bmatrix} x \\ y \end{bmatrix} = \begin{bmatrix} 2 & -1 \\ 1 & 3 \end{bmatrix} \begin{bmatrix} x \\ y \end{bmatrix} = \begin{bmatrix} 2x -y\\ x + 3y \end{bmatrix} = \begin{bmatrix} -8 \\ -11 \end{bmatrix}

\begin{bmatrix} x \\ y \end{bmatrix}


\begin{bmatrix} x \\ y \end{bmatrix} = \begin{bmatrix} - \frac{24}{7} & - \frac{8}{7} \\ \frac{11}{7} & - \frac{22}{7} \end{bmatrix}




\begin{bmatrix} x \\ y \end{bmatrix} = \begin{bmatrix} - \frac{24}{7} - \frac{11}{7} \\ \frac{8}{7} - \frac{22}{7} \end{bmatrix} = \begin{bmatrix} -5 \\ -2 \end{bmatrix}
