Consider the matrix

$\displaystyle

A = \left[\begin{matrix}1 & -2\\1 & 3\end{matrix}\right]

$

Consider the matrix norm $\displaystyle ||\cdot||_{ind}$ induced by the $\displaystyle 1-norm$ on the domain and the $\displaystyle \infty-norm$ on the range. Applied to A, we have that:

a) $\displaystyle ||A||_{ind}=5$

b) $\displaystyle ||A||_{ind}=\sqrt{15}$

c) $\displaystyle ||A||_{ind}=4$

d) $\displaystyle ||A||_{ind}=3$

thanks again.
