1. let S={pP3:p(0)=0}. One of the following is a basis for S. (a) {1,x,x2} (b) {x,x2} (c) {x2+x} (d) {x2+1} 2. Let A=000110201, then (a) A is in REF (b) nullity(A)=2 (c) rank(A)=2 (d) det(A)=0 3. The vectors {2,x,sinx} in C[0,2] are (a) Linearly independent (b) Linearly dependent (c) A basis for C[0,2] (d) A spanning set for C[0,2] 4. Consider the ordered basis E={e1,e1e2} for R2. If [v]E=(1,1)T, then v= (a) e2 (b) 2e1+e2 (c) e1+e2 (d) (0,1)T
