Q. Consider this matrix transformation:[21−13]What is the image of [23] under this transformation?
Write Matrix Transformation: Write down the matrix transformation and the vector to be transformed.Matrix transformation: [2amp;−11amp;3]Vector: [23]
Perform Matrix Multiplication: Perform matrix multiplication to find the image of the vector under the transformation.To multiply the 2×2 matrix by the 2×1 vector, we take the dot product of the rows of the matrix with the columns of the vector.First row of the matrix times the vector: (2×2)+(−1×3)=4−3=1Second row of the matrix times the vector: (1×2)+(3×3)=2+9=11
Write Resulting Vector: Write down the resulting vector, which is the image of the original vector under the transformation.The resulting vector (image) is: \left[\begin{array}{c}1\11\end{array}\right]
