+        \begin{enumerate}
+            \item $k(x_1,x_2)=C=\sqrt{C}^2\cdot k'(x_1,x_2)$, where $k'(x_1,x_2)=1$ which is clearly positive semidefinite.
+            \item is p.d. according to the lecture, because it's a polynomial kernel
+            \item TODO: don't see why not in the hint-case
+            \item As 2. is a kernel, this is too with $\alpha=\sqrt{5}$
+            \item As $k_1(x_1,x_2)=x_1^Tx_2$ and $k_2(x_1,x_2)=1$ are kernels, their sum is too. Now we multiply the sum of this kernels with itself and get another kernel.
