Part B needed with all sub parts Needed to be solbed part B correctly in 1 hour and get the thumbs up please show me neat and clean work for it Thank you
A. Is it a Subspace?
Consider the following vector spaces V and subsets U. Determine if U is a subspace of V.
Make sure to justify your findings.
1. U₁ = Set of 3 x 3 upper triangular matrices.
V₁ = Set of all 3 x 3 matrices.
(You may consider regular matrix addition and scalar multiplication.)
2. U₂ = Set of quadratic polynomials whose coefficients add up to 1.
(examples: 3x²+2x − 4; x² − x + 1; 4x − 3)
V₂ = P(2), set of all quadratic polynomials (ax² + bx + c)
3. U3
V3
Set of 4 x 4 diagonal matrices.
Set of all 4 x 4 matrices.
B. Independently Linear
Which of the following sets of vectors are linearly independent? Explain your steps.
1. S₁ =
2. S₂ =
{][*]}
3. S3 = {(x² + 3x + 1), (x² − 2x), (3x² − x+1)}
C. All about that Basis
For each of the following sets of vectors S in a vector space V:
(i) Describe the subspace spanned by the set S.
(ii) Determine the dimension of Span(S).
(iii) Modify the set S to form a basis for V.
6
1. S₁ = {(1,0, -2, 1), (0, 1, 0, 1), (1, 2, -2,3)} in V₁ = R¹.
2. S₂ = {³-3x, 3x, x² - 2} in V₂ = P(3) (i.e., the space of polynomials of degree at
most 3)
