Question 4
Extracted text: Use a graphing utility or computer software program with matrix capabilities to write v as a linear combination of u1, u2, U3, U4, U5 and Ug. Then verify your solution. u1 = (2, 3, -1, -4, 1, 4) u2 = (3, -3, 3, -1, 1, 1) U3 = (4, 1, -1, -2, -2, 4) U4 = (2, 1, -4, 3, 3, 4) Us = (4, -1, -4, 3, -2, 4) U6 = (4, 1, -4, 4, 2, 2) v = (3, 30, -5, -21, 26, 13) V =
