Can someone please explain to me ASAP??!!!
Transcribed Image Text:To be a subspace H of V, the following must all be true
i. 0 (the zero vector) is in H
ii. It is closed under addition. i.e. if u, v are in H, then u + v are in H
iii. It is closed under scalar multiplication. i.e if u is in H, then for any constant c, cu is in H
The following is NOT subspace.
The set of all polynomials of at most second degree, p(t) = ao + a₁t + a₂t² with rational
coefficients.
Explain WHY it fails to be subspaces.
To do this, all you need to do is come up with ONE specific example that makes one of the statements
above false.
Since most of you are new to this, this question will "guide" you through the steps.
i. Is the 0 vector in the set?
If so, what is 0 (that is, what are the values for all the coefficients, ao, a1, a2?
If not, why is o not in the set?
