a. A basis for the null space of A is {
}. You
<4,2>
should be able to explain and justify your
answer. Enter a coordinate vector, such as
<1,2> or <1,2,3,4>, or a comma
separated list of coordinate vectors, such as
<1,2>,<3,4> or <1,2,3,4>,<5,6,7,8>.
b. The dimension of the null space of A is
because (select all
correct answers -- there may be more than
one correct answer):
O A. Two of the four columns in rref(A)
have pivots.
B. rref(A) is the identity matrix.
C. rref(A) has a pivot in every row.
D. Three of the four columns in rref(A)
do not have a pivot.
E. rref (A) has three free variable
columns.
F. rref(A) has one free variable column.
G. The basis we found for the null space
of A has three vectors.
c. The null space of A is a subspace of
R^4
because
A has 4 columns
d. The geometry of the null space of A is
