Limits Discontinuities E6B5A1
1. The problem asks to find the limits of the function $f(x)$ as $x$ approaches several points where the function has discontinuities.
2. Recall that 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, if it exists.
3. Since the function has many discontinuities, we must consider the left-hand limit $\lim_{x \to a^-} f(x)$ and the right-hand limit $\lim_{x \to a^+} f(x)$ at each point $a$. If these two limits are equal, the limit exists and equals that value; otherwise, the limit does not exist.
4. From the graph description:
- At $x = -2$, the function appears continuous or has a defined limit; assume $\lim_{x \to -2} f(x) = L_1$.
- At $x = 0$, there is a discontinuity; check left and right limits.
- At $x = 2$, similarly check left and right limits.
- At $x = 4, 5, 6, 8, 10, 11$, the graph shows vertical jumps or arrows indicating discontinuities.
5. Without exact function values, we interpret the graph's behavior:
- $\lim_{x \to -2} f(x) = f(-2)$ if continuous.
- $\lim_{x \to 0} f(x)$ does not exist if left and right limits differ.
- Similarly for other points.
6. Since the problem does not provide explicit function values or formulas, the limits at these points are determined by the graph's behavior:
- $\lim_{x \to -2} f(x) = $ value at $x=-2$ (assumed continuous).
- $\lim_{x \to 0} f(x)$ does not exist due to jump.
- $\lim_{x \to 2} f(x)$ does not exist due to jump.
- $\lim_{x \to 4} f(x)$ does not exist due to vertical jump.
- $\lim_{x \to 5} f(x)$ does not exist due to vertical jump.
- $\lim_{x \to 6} f(x)$ does not exist due to vertical jump.
- $\lim_{x \to 8} f(x)$ does not exist due to vertical jump.
- $\lim_{x \to 10} f(x)$ does not exist due to vertical jump.
- $\lim_{x \to 11} f(x)$ does not exist due to vertical jump.
7. Therefore, the only limit that likely exists is at $x = -2$; all others do not exist due to discontinuities.
Final answers:
$$\lim_{x \to -2} f(x) = f(-2)$$
$$\lim_{x \to 0} f(x) \text{ does not exist}$$
$$\lim_{x \to 2} f(x) \text{ does not exist}$$
$$\lim_{x \to 4} f(x) \text{ does not exist}$$
$$\lim_{x \to 5} f(x) \text{ does not exist}$$
$$\lim_{x \to 6} f(x) \text{ does not exist}$$
$$\lim_{x \to 8} f(x) \text{ does not exist}$$
$$\lim_{x \to 10} f(x) \text{ does not exist}$$
$$\lim_{x \to 11} f(x) \text{ does not exist}$$
