Question: Suppose that V1 = 1 V2: (b) Is the vector z V3 - 2 1 2 ,V4 and let B = [V1 V2 V3

Suppose that V1 = 1 V2: (b) Is the vector z V3

Suppose that V1 = 1 V2: (b) Is the vector z V3 - 2 1 2 ,V4 and let B = [V1 V2 V3 V4] be the matrix that has vector v; as its i-th column (1 i 4). (a) Does B have an inverse? Why or why not? 2 in Null B? Why or why not? (c) Is S = {V, V3, V4} a basis for Col B? Why or why not?
