`|[42, 1, 6],[ 28, 7, 4], [14 ,2, 2]|=?`

Evaluate the following: |[42,1,6],[28,7,4],[14,3,2]|

Evaluate the following: |[42,1,6],[28,7,4],[14,3,2]|

Using the property of determinants and without expanding prove the following |{:(42,1,6),(28,7,4),(14,3,2):}|=0

Without expanding show that the following determinants vanish |(42,1,6),(28,7,4),(14,3,2)|

Which of the following relations are functions? Give reasons. If it is a function, determine its domain and range. {(2,1), (4,2), (6,3), (8,4), (10,5), (12,6), (14,7)}

Find the rank of the matrix A = [[2,4,3,-2],[-3,-2,-1,4],[6,-1,7,2]]
