1. Let v1 = [-3; 3; -4], v2 = [3; -2; 8] and y = [-12; 9; h]
For what value of is in the plane spanned by and ?
2. Which of the following sets are subspaces of ?
B. arbitrary number
C. arbitrary number
D. arbitrary number
Check all that apply.
Sort of desperate for help
Thanks in advance!
A subspace must be closed under scalar multiplication and vector addition. So, for example F. is not a subspace since if we let then surely but since has the quality that we see that . But, this HAS to happen in a subspace. So, is not a subspace.
