The determinant of C is zero and does not have inverse.
Step-by-step explanation:
Let
, since it is a matrix with 3 rows and 3 columns, we can determine its determinant by the Sarrus' rule:
Since the determinant of C is equal to zero, then we conclude that C does not have an inverse according to the following definition of inverse matrix. That is:
Where
is the adjugate matrix of C, defined as the transpose of the cofactor matrix of C.
The result of this expression is undefined due to the determinant.
