Evaluate each expression using the given graph of $f(x)$. Enter DNE if the limit or value does not exist. If you are having a hard time seeing the picture clearly, click on the picture. It will expand to a larger picture on its own page so that you can inspect it more clearly.

1. $\displaystyle \lim_{x \to 1^{-}}f(x) =$
2. $\displaystyle \lim_{x \to 1^{+}}f(x) =$
3. $\displaystyle \lim_{x \to 1}f(x) =$
4. $\displaystyle \lim_{x \to -1^{-}}f(x) =$
5. $\displaystyle \lim_{x \to -1^{+}}f(x) =$
6. $\displaystyle \lim_{x \to -1}f(x) =$
   In problems g-i, assume $a$ is an integer such that $-3 \leq a \leq 3$.
7. $\displaystyle \lim_{x \to a^{-}}f(x) =$
8. $\displaystyle \lim_{x \to a^{+}}f(x) =$

1. $\displaystyle \lim_{x \to a}f(x) =$
