True of False a The span of v1 vn is the column space of

True of False?

(a) The span of v1, . . . , vn is the column space of the matrix

whose column vectors are v1, . . . , vn.

(b) The column space of a matrix A is the set of solutions of

Ax = b.

(c) If R is the reduced row echelon form of A, then those column

vectors of R that contain the leading 1

Solution

a, c , h, g ,i are true

b, d, e, f, j are false
