We have a function,
and we are asked to find its inverse function.
An inverse function essentially gets you the original value that was dropped into a function.
For example,
If I put 5 into I will get 24. Now If I take 24 and put it into the inverse function I have to get number 5 back.
The way to determine the inverse function swap the x and the , then solve for
,
Of course the notation demands that the obtained function be called,
Hope this helps :)
Answer:
So, option A is correct.
Step-by-step explanation:
To find the inverse of the matrix, the formula is:
Inverse of the matrix exists if |A| does not equal to 0
|A| = 7 * 9 -( -2 * -10)
|A| = 63 - 20
|A| = 43
AS |A| ≠ 0
so inverse exist.
now finding Adj A
=
So, option A is correct.
The equivalent expressions are ~
