For the given system, determine which is the case. joe frazier grandchildren If ~u is in S and c is a scalar, then c~u is in S (that is, S is closed under multiplication by scalars). It may be obvious, but it is worth emphasizing that (in this course) we will consider spans of finite (and usually rather small) sets of vectors, but a span itself always contains infinitely many vectors (unless the set S consists of only the zero vector). Previous question Next question. Experts are tested by Chegg as specialists in their subject area. I think I understand it now based on the way you explained it. such as at least one of then is not equal to zero (for example R3 and so must be a line through the origin, a
