If you want to enhance your academic performance, start by setting realistic goals and working towards them diligently. Hence \(f\) is surjective, so every element \(t \in T\) has at least one pre-image. They can provide you with the guidance and support you need to succeed. This follows from the distributivity of matrix multiplication over addition. Suppose \(L\) is \emph{not} injective. In other words, \(\ker L=\{0\}\), and so \(L\) is injective.
