Let T:  R3 → R3 be a linear transformation and I be the identify transformation of  R3. If there is a scalar C and a non-zero vector x ∈ R3 such that T(x) = Cx, then rank (T – CI) 
  • a)
    cannot be 0 
  • b)
    cannot be 2 
  • c)
    cannot be 3
  • d)
    cannot be 1 
Correct answer is option 'C'. Can you explain this answer?

By rank-nullity is theorem, 
dim(T) = Rank(T) + Nullity (T) 
Here dim(T) = 3 Now, (T – CI)x = T(x) – (T(x) = cx – cx 
= 0
(I is identity transformation) 
⇒ Nullity of T – CI cannot be zero 
⇒ Hence, Rank of T – CI cannot be 3.
