The linear transformation T: R" → RM is defined by T(v) = Av, where A is as follows.
A =
0 1 -8 1
-1 6 3 0
0 1 5 1
(a) Find T(1, 3, 2, 0).
STEP 1: Use the definition of T to write a matrix equation for T(1, 3, 2, 0).
T(1, 3, 2, 0) =
STEP 2: Use your result from Step 1 to solve for T(1, 3, 2, 0).

T(1, 3, 2, 0) =
(b) Find the preimage of (0, 0, 0).
STEP 1: The preimage of (0, 0, 0) is determined by solving the following equation.
T(w, x, y, z) =
W =
