Recall that to find the matrix A of T, we apply T to each of the standard basis vectors →ei of R4. The result is the 2 × 4 matrix A given by A = [1 0 0 1 0 1 1 0] Fortunately, this matrix is already in reduced row-echelon form. The rank of A is 2. diamond shape princessWebTo show a function is not surjective we must show f(A) 6=B. Since a well-de ned function must have f(A) B, we should show B6 f(A). Thus to show a function is not surjective it is enough to nd an element in the codomain that is not the image of any element of the domain.
