Let f : \mathbb{r}^{2} \to \mathbb{r}^{2} be the linear transformation defined by f(\vec{x}) = \left[\begin{array}{cc} 4 & 3\cr 2 & 1 \end{array}\right] \vec{x}. let \begin{array}{lcl} \mathcal{b} & = & \lbrace \left< 1,-1\right> , \left< 2,-3\right> \rbrace, \\ \mathcal{c} & = & \lbrace \left< 1,1\right> , \left< -2,-1\right> \rbrace, \end{array} be two different bases for \mathbb{r}^{2}. find the matrix \lbrack f \rbrack_{\mathcal{b}}^{\mathcal{c}} for f relative to the basis \mathcal{b} in the domain and \mathcal{c} in the codomain.
