Only one of the following matrix has an inverse. Find the determinant of each matrix, and use the determinant to identify the one that has an inverse. Then find the inverse.
The determinant of the given matrices and identify which one has an inverse.
Two matrices are
The determinant of matrix is given by
A given matrix has an inverse if and only if its determinant is non-zero.
Consider the matrix
Since therefore, it doesn’t have an inverse
