Q. Consider this matrix transformation:⎣⎡2−33−1⎦⎤What is the image of [41] under this transformation?
Identify Matrix and Vector: Identify the matrix and the vector to be transformed. Matrix A=[2amp;3−3amp;−1] Vector v=[41]
Perform Matrix Multiplication: Perform matrix multiplication to find the image of the vector.Image of v, Av = \begin{bmatrix}2 & 3\-3 & -1\end{bmatrix} * \begin{bmatrix}4\1\end{bmatrix}To multiply, take the dot product of the rows of A with the columns of v.
Calculate First Element: Calculate the first element of the resulting vector.First element = (2×4)+(3×1)=8+3=11
Calculate Second Element: Calculate the second element of the resulting vector.Second element = (−3×4)+(−1×1)=−12−1=−13
Combine Results: Combine the results to get the image of the vector.The image of \begin{bmatrix}4\1\end{bmatrix} under the transformation is \begin{bmatrix}11\-13\end{bmatrix}.
