Limit Analysis 2Dcbfa
1. **State the problem:** We need to find the limits of the function $f(x)$ as $x$ approaches $-2$, $0$ from the left and right, and $2$ from the left and right.
2. **Recall the definition of limits:** The limit $\lim_{x \to a} f(x)$ is the value that $f(x)$ approaches as $x$ gets arbitrarily close to $a$ from both sides.
3. **Analyze each limit using the graph description:**
- $\lim_{x \to -2} f(x)$: The graph has a vertical asymptote near $x=-2$ with the curve moving steeply upward approaching it from the left. This means the limit does not exist because the function tends to infinity.
- $\lim_{x \to 0^-} f(x)$: As $x$ approaches $0$ from the left, the graph oscillates around $y=1$ with sharp waves. Since it oscillates and does not approach a single value, the limit does not exist.
- $\lim_{x \to 0^+} f(x)$: Similarly, from the right side of $0$, the graph oscillates around $y=1$ and does not approach a single value, so the limit does not exist.
- $\lim_{x \to 2^-} f(x)$: Approaching $2$ from the left, the graph jumps to around $y=3$ (filled circle), so the limit from the left is $3$.
- $\lim_{x \to 2^+} f(x)$: Approaching $2$ from the right, there is an open circle just below at $y=1$, so the limit from the right is $1$.
4. **Summary of limits:**
$$\lim_{x \to -2} f(x) \text{ does not exist}$$
$$\lim_{x \to 0^-} f(x) \text{ does not exist}$$
$$\lim_{x \to 0^+} f(x) \text{ does not exist}$$
$$\lim_{x \to 2^-} f(x) = 3$$
$$\lim_{x \to 2^+} f(x) = 1$$
