I'm confused by this question:
The question only mentions x and y so I assume this is supposed to be an transformation but the matrix is a 3x3.. don't see how the multiplication would work.A transformation T in the plane consists of a reflection in the line x + y = 0 followed by a translation in which the point (x,y) is transformed to the point (x+h,y+k).
(a). Show that the matrix representing T is
I tried transforming the unit square but didn't do much to help me understand.
