Consider the vectors 4 4 U1 , U2 2 = -12 , u4 = 11 8 8 5 and the vector w = 1 2 If w IS in the span of u1, U2, u3, u4, write w as a linear combination of u1, U2, u3, u4 , using as few nonzero coefficients as possible. If w IS NOT in the span of u1, U2, U3, u4 , write DNE in each of the answer boxes. w ugt U3+
