Question

Select the matrix multiplication that transforms vector A to
vector B

Answer 1

Answer:

Option C.

Step-by-step explanation:

Notice that only option B and C involves the vectors in transformation

$A=\begin{bmatrix}4\\2\end{bmatrix}, B=\begin{bmatrix}-8\\-4\end{bmatrix}$

However, option B is not a defined multification since the dimension of both matrices are not matching. Vector A is 2x1 but the second matrix is 2x2.
