1. Range is defined as
R(T ) := {(x+2y−z+w,−x−2y+z−2w, x+2y−z) ∈ R3 : x, y, z, w ∈ R}
Let y = z =
w = 0 and x = 1 then we have
x + 2y − z + w = 1
−x− 2y + z − 2w = −1
x + 2y − z = 1
Hence we see that (1,−1, 1) ∈ R(T ) is a non zero element.
2. In R4, define the hyperlane H1, H2 and H3 by:
H1 := {(x, y, z) : x− y + z = 0}
H2 := {(x, y, z) : 2x− 2y + 2z = 0}
H3 := {(x, y, z) : −x + y − z = 0}
H4 := {(x, y, z) : x− 2y =...
