Use the Matrix Capabilities of a Graphing Utility to Find

Use the matrix capabilities of a graphing utility to find AB, if possible. $$A = \left[ \begin{array} { c c c } - 7 & - 2 & - 8 \\2 & - 9 & 3 \\- 7 & - 8 & 6\end{array} \right] , B = \left[ \begin{array} { c c c } 4 & 4 & 1 \\- 9 & - 5 & 3 \\3 & - 2 & - 5\end{array} \right]$$

A) $\left[ \begin{array} { c c c } - 28 & - 8 & - 8 \\- 18 & 45 & 9 \\- 21 & 16 & - 30\end{array} \right]$
B) $\left[ \begin{array} { c c c } 14 & - 34 & - 53 \\116 & 59 & - 10 \\26 & 24 & - 1\end{array} \right]$
C) $\left[ \begin{array} { c c c } - 34 & 98 & 62 \\- 2 & 47 & 0 \\27 & - 40 & - 61\end{array} \right]$
D) $\left[ \begin{array} { c c c } - 34 & - 2 & 27 \\98 & 47 & - 40 \\62 & 0 & - 61\end{array} \right]$
E) not possible
