`A` is an involuntary matrix given by `A=[0 1-1 4-3 4 3-3 4]` , then the inverse of `A//2` will be `2A` b. `(A^(-1))/2` c. `A/2` d. `A^2`

A

`2A`

B

`A^(-1)/2`

C

`A/2`

D

`A^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`because` A is involutory
`therefore A^(2) I rArr A = A^(-1)`
`therefore (A/2)^(-1) = 2 A^(-1) = 2 A `
