Homework Statement
Find a 3x3 matrix produces the following 2D composites transformation by translation and reflection about the line x=-3
The attempt at a solution
I understand translation but how do you go about doing reflection? I'm guessing for reflection, I need to do a conjugation? So I need to move the line from the origin to x=-3.Do I simply multiply -3 to the standard matrix of the line about x?
I have asked in another site but no one seems to be answering. Any kind of help will be appreciated.
