Which of the following applies? (Note, only 1 answer) A) The number 2 is an eigenvalue of the transformation and its geometric multiplicity is 3. B) The number 2 is an eigenvalue of the transformation, with algebraic multiplicity 3. For the transformation to be diagonalizable, its geometric multiplicity must be 3. C) The number 2 is an eigenvalue of the transformation, but since the transformation does not have 6 different eigenvalues, it cannot be diagonalizable. D) We cannot know whether the number 2 is an eigenvalue or not.

2:
A linear transformation F: R5 → R5 is given in the standard base of a matrix A. Suppose you
calculate the secular polynomial and get det (A − 2) = (2-3)(a − 2)³(λ — 1). Which of the
following applies? (Note, only 1 answer)
A) The number 2 is an eigenvalue of the transformation and its geometric multiplicity is 3.
B) The number 2 is an eigenvalue of the transformation, with algebraic multiplicity 3. For the
transformation to be diagonalizable, its geometric multiplicity must be 3.
C) The number 2 is an eigenvalue of the transformation, but since the transformation does not
have 6 different eigenvalues, it cannot be diagonalizable.
D) We cannot know whether the number 2 is an eigenvalue or not.
