SOLUTION: Consider the following matrix. A = 2, 0, 3, 1, 1, -1, 0, 1, -2, Choose the correct description of A Find A^−1 if it exists.

Question 1068624: Consider the following matrix.
A =
2, 0, 3,
1, 1, -1,
0, 1, -2,

Choose the correct description of A
Find A^−1 if it exists.
Answer either Choice 1, or Choice 2:
