Why is water leaking from this hole under the sink? The kernel can be found in a 2 2 matrix as follows: L = [ a b c d] = ( a + d) + ( b + c) t Then to find the kernel of L we set ( a + d) + ( b + c) t = 0 d = a c = b so \(\textit{(Bijectivity \(\Rightarrow\) existence of an inverse.)}\). Note that $T(0,0,1)=(0,0)$ and so $(0,0,1)$ is definitely in the kernel. say a linear transformation T: Possible Answers: None of the other answers.
