d) Let x = (1, 2, 3) C3 be arbitrary and let a = (a1, 02, 03) € C³, b= (b₁,b2, b) C³ be fixed. Let a1 a2 a3 TH-4639 T(x)= det b₁ b₂ b3 22 23/ Find T(303). ii) Use the symbol T(x) to explain what it means that the determinant of 3 x 3 matrix is a linear map with respect to the third row. iii) Use the result in the preceding part, or otherwise, to prove that T(x) = 0, if x E span {a, b}. Hint: You can use without proof the fact that the determinant of a 3 x 3 matrix with two identical rows is zero.
