1. The problem is to understand the function $h(n)$ given by the values $2, -1, 1, 1, 0$. 2. Since $h(n)$ is given as a sequence of values, we interpret it as $h(1)=2$, $h(2)=-1$, $h(3)=1$, $h(4)=1$, and $h(5)=0$. 3. There is no explicit formula provided, so the function is defined by these discrete points. 4. If you want to express $h(n)$ as a piecewise function, it can be written as: $$ h(n) = \begin{cases} 2 & \text{if } n=1 \\ -1 & \text{if } n=2 \\ 1 & \text{if } n=3 \\ 1 & \text{if } n=4 \\ 0 & \text{if } n=5 \end{cases} $$ 5. This defines $h(n)$ completely for $n=1$ to $5$. 6. If you need further operations or analysis on $h(n)$, please specify.
