Given : and f(x) = x2 – 5x + 7.

Matrix A is of order 2 2.

To find : f(A)

Formula used : Where cij = ai1b1j + ai2b2j + ai3b3j + ……………… + ainbnj

A2 is a matrix of order 2 x 2.

f(x) = x2 – 5x + 7

f(A) = A2 – 5A + 7I

A2 = = = A2 = 5A = 5 × = 5A = 7I = 7 × = 7I = f(A) = A2 – 5A + 7I = + = f(A) = A2 – 5A + 7I = f(A) = A2 – 5A + 7I = Rate this question :
