Prove that V is a subspace of R4
Actual problem is attached
- S contains a zero element
- for any x in V and y in V, x + y is in V
- for any x in V and scalar k, kx is in V
The Attempt at a Solution
Its obvious that V is a subset of R4. And I know I must prove that is it contains zero vector which is obvious. But how to I prove its closure, I can see that it is by looking but how exactly do I denote it?
