Hey,
I am having trouble seeing why the following is not a vector space.
"The set of all first-degree polynomial functions , , whose graphs pass through the origin with the standard operations"
By #4 " has a zero vector 0 such that for ever u in , u+0=u"
I am not seeing why #4 keeps the above from being a vector space. I don't think I am understanding the zero vector as I should.
Thanks
