Throughout this question, fix A as an n×n matrix. If f(x) is a polynomial, then f(A) is the expression formed by replacing every x in f(x) with A and inserting the n×n identity matrix I to its constant term. For example, if f(x) = x2 −2x+5 (whose degree is 2), then f(A) = A2 −2A+5I; if f(x) = −x3 +2 (whose degree is 3), then f(A) = −A3 + 2I. (a) Using induction of the degree of the polynomial f(x),...
