In each case, show that T-2 = 1 and find (as in Example 10) an ordered basis B such that Mb(T) has the given block form.
(a) T: M22 †’ M22 where T(A) = AT,

(b) T : P3 †’ P1 where 7[p(x)] = p(-x),

(d) T: IR3 †’ IR3 where T(a, b, c) =
(-a + 2b + c, b + c, -c), MB(T)

(e) T: V †’ V where
T(v) = -v, dim V = n, MB(T) = -1n

MB(T) =
