Operations with Matrices In Exercises 67-72, use a graphing utility to perform the operations for the matrices A, B, and C and the scalar c. Write a brief statement comparing the results of parts (a) and (b).

\(A=\left[\begin{array}{rrr}1&2&-1\\ 0&-2&3\\ 4&-3&2\end{array}\right],\quad\ \ B=\left[\begin{array}{rrr}2&3&0\\ 4&1&-2\\ -1&2&0\end{array}\right],\)

\(C=\left[\begin{array}{rrr}3&-2&1\\ -4&0&3\\ -1&3&-2\end{array}\right],\)                                                                       and    c = 3

(a) A(B + C)                          (b) AB + AC

A = [ _4  -3  2  ^0  -2  3  ^^1  2  -1],  B = [ _-1  2  0  ^4  1  -2  ^^2  3  0]

C = [ _-1  3  -2  ^-4  0  3  ^^3   -2  1]
