Problem 15. Let A be an m x n matrix over R. We define NA := {x € R" : Ax = 0}. NA is called the kernel of A and v(A) := dim(NA) is called the nullity of A. If NA only contains the zero vector, then v(A) = 0. (i) Let %3D a- (; i 3) 1 2 2 -1 Find NA and v(A). (ii) Let --() 3 A = 4 6 3 -69 Find NA and v(A).
