Let A be a matrix with columns col1 and col2Consider points T,U,V,W in the output grid below
Then what is the list A−1→T,A−1→U,A−1→V,A−1→W?
Let's see you have a go at this, making use of the answer I gave here: https://web2.0calc.com/questions/please-help-thank-you_42#r1
Note that
A-1 = [ 0 1]
[-1 0]
T = [-1]
[-1]
U = [2]
[3]
V = [3]
[1]
W = [ 2]
