Resposta:
Opção 1.
Explicação passo a passo:
Matriz [tex]C_{3\times3}[/tex], com [tex]c_{ij}=3i-2j[/tex].
Ilustrando os elementos de uma matriz genérica de ordem 3:
[tex]C=\left[\begin{array}{ccc}c_{11}&c_{12}&c_{12}\\c_{21}&c_{22}&c_{23}\\c_{31}&c_{32}&c_{33}\end{array}\right][/tex]
Calculando os elementos pela fórmula, teremos:
[tex]c_{11}=3\cdot1-2\cdot1=3-2=1\\\\c_{12}=3\cdot1-2\cdot2=3-4=-1\\\\c_{13}=3\cdot1-2\cdot3=3-6=-3\\\\c_{21}=3\cdot2-2\cdot1=6-2=4\\\\c_{22}=3\cdot2-2\cdot2=6-4=2\\\\c_{23}=3\cdot2-2\cdot3=6-6=0\\\\c_{31}=3\cdot3-2\cdot1=9-2=7\\\\c_{32}=3\cdot3-2\cdot2=9-4=5\\\\c_{33}=3\cdot3-2\cdot3=9-6=3[/tex]
Portanto:
[tex]C=\left[\begin{array}{ccc}1&-1&-3\\4&2&0\\7&5&3\end{array}\right][/tex]
