Limits From Graph
1. Stating the problem: We are asked to find two limits based on the description of the graph of a function $f(x)$.
2. For part (a), find $\lim_{x \to 0} f(x)$.
- The graph passes through the origin (0,0).
- Since the function is continuous, the limit at $x=0$ is simply the function value at 0.
- Thus, $\lim_{x \to 0} f(x) = 0$.
3. For part (b), find $\lim_{x \to 2} f(x)$.
- The graph shows a solid dot at approximately $(2,-3)$.
- This indicates the function value at 2 is $f(2) = -3$.
- However, there is also an open circle near $(2,1)$, indicating a hole/discontinuity at that point.
- The limit $\lim_{x \to 2} f(x)$ depends on where the function values approach as $x$ approaches 2.
- Since the graph decreases through $(2,-3)$ with a solid dot and there's a hole at $(2,1)$, the limit equals the value of the function approaching 2.
- Since the open circle suggests the value at 1 is not included, but the function approaches $-3$, the limit is $-3$.
4. Final answers:
- $\boxed{\lim_{x \to 0} f(x) = 0}$
- $\boxed{\lim_{x \to 2} f(x) = -3}$
These values match the continuity and the provided points on the graph.
