# Math Help - vector space

1. ## vector space

let me take a funtion that vanish at end points x=0 and x=L. do these functions qualify to be a vector space?
i proceeded this way - to show that they qualify, i have to show that they are closed, commutative etc. i think they are not closed. so they dont form vector space.am i correct??
and functions that obey f(0)=5?(hints please)
many thanks.

What kind of functions? What is L? You must write questions more clearly and giving information
