Document Summary

The reverse side of pages is for scrap work. If you nd that you need extra space in order to answer a particular question, you should continue on the reverse side of the page and indicate this clearly. Please do not write in the table below. Note that more than one set may be a subspace. Here n = 3. (d) the set {(c + 5, c) | c r}. Here n = 2. (e) the span of 5 vectors in r4. Here n = 4. (f) the set {(x2, x) | x r}. Note that more than one statement may be false. [2 points] suppose a and b are 3 3 matrices with det a = 2 and det b = 1. B = a b c d 5a e 5b f 5c. The reduced row echelon form of a is. 0 0 0 0 0 (a) [2 points] find a basis of nul a.
