Answer:

  [[-14][-1]]

Step-by-step explanation:

Row m of the first matrix is multiplied term-by-term by column n of the second matrix to get term (m,n) of the product matrix.

  $\left[\begin{array}{cc}2&-4\\3&-1\end{array}\right]\times\left[\begin{array}{c}1&4\end{array}\right] =\left[\begin{array}{c}(2)(1)+(-4)(4)&(3)(1)+(-1)(4)\end{array}\right] =\left[\begin{array}{c}-14&-1\end{array}\right]$
