f(x) = x2-5x+ 6 .. find f(A) if A= matrix 2 0 1 2 1 3 1 -1 0 Share with your friends Share 12 Manbar Singh answered this We have,fx = x2 - 5x + 6So, fA = A2 - 5A + 6IA = 2012131-10A2 = A . A = 2012131-102012131-10 = 4+0+10+0-12+0+04+2+30+1-32+3+02-2+00-1+01-3+0 = 5-129-250-1-2-5A = -52012131-10 = -100-5-10-5-15-550 6I = 6100010001 = 600060006Now, A2 - 5A + 6I = A2+-5A+6I = 5-129-250-1-2 + -100-5-10-5-15-550 + 600060006 = 1-1-3-1-1-10-544 46 View Full Answer Jigar answered this f (A) = A^2 -5A +6I where I is an identity matrix ! 15
