Question: 1 -17 3. Consider A = 1 4 2 (a) Denote the span of the column vectors of A as linear combinations of the column

1 -17 3. Consider A = 1 4 2 (a) Denote the span of the column vectors of A as linear combinations of the column vectors. (b) Let b = , where s is a real number. Using elimination, determine the condition (or 3 conditions) on s that ensures that b is in the span of the column vectors of A (namely, Ax = b has a solution). (c) Do the column vectors of A span a line, plane or volume
