Question:

Determine which of the following sets of vectors x = (x1, x2, . . . , xn)T are subspaces of Rn:

(a) All equal entries x1 = · · · = xn

(b) All positive entries: xi ≥ 0; 

(c) First and last entries equal to zero: x1 = xn = 0; 

(d) Entries add up to zero: x1 + · · · + xn = 0; 

(e) first and last entries differ by one: x1 − xn = 1.
