What are a (v₁) for i = 1, 2, 3, 4 as elements of W?
these bases is A =
Select one:
a(v₁) = W₂ w3, α(v₂) = 2w₁, a(v3) = −W₁ - W₂ +3w3, a(v₁) = 3w3
O
None of the others apply
This is not possible as the matrix A is 3 x 4 so only three of the a(v₂) can be defined by it
a(v₁) = W₂ - w3, α(v₂) = W₁ — W3, a(v3) = −w₁ + 3w3, a(v₁) = 3w3
O
a(v₁) = W₁ w3, α(v₂) = w₁ +3w₂ +3w3, a(v3) = 2w₂, α(v₁) = w₁ +2w3
