Determine whether $T$ is a linear transformation. $$T: M_{n n} \rightarrow \mathbb{R} \text { defined by } T(A)=\operatorname{tr}(A)$$
Determine whether the function is a linear transformation. Justify your answer. $$T: M_{m n} \rightarrow R, \text { where } T(A)=\operatorname{tr}(A)$$
Verify directly from Definition 6.1 .3 that the given mapping is a linear transformation. $T: M_{n}(\mathbb{R}) \rightarrow \mathbb{R}$ defined by $T(A)=\operatorname{tr}(A),$ where $\operatorname{tr}(A)$ denotes the trace of $A$.
