Question

Using the graph, find each limit or explain why the limit does not exist. a. lim x-> -1f(x) b. lim x -> 1f(x) c. lim x -> 0+f(x) d. lim x -> 2f(x) 

**Graph Explanation: Piecewise Function**

This diagram illustrates a piecewise function on a coordinate plane. Here’s a detailed breakdown of each component of the graph:

### Axes and Scale:

- **X-Axis (Horizontal):** The x-axis ranges from -2 to 2.
- **Y-Axis (Vertical):** The y-axis ranges from -2 to 4.
- Both axes intersect at the origin (0,0).

### Graph Description:

1. **Left Segment:**
   - A curve begins from the top-left and moves downward, approaching the point (-1, 1).
   - There is an open circle at (-1, 1) indicating that this point is not included in the function.

2. **Vertical Section:**
   - The graph exhibits a vertical movement from the open circle at (-1, 1) downwards, connecting to the negative region of the y-axis at around (0, -1).
   - An open circle is present at the origin (0, 0), denoting the exclusion of this point.

3. **Right Segment:**
   - From the open circle at the origin, a new curve emerges moving upward to the right.
   - The curve includes an open circle at the point (1, 1).

4. **Isolated Point:**
   - A filled black circle is plotted at (1, -1), representing a specific inclusion of this point in the function.

### Summary:

This graph clearly illustrates a piecewise function with specific intervals and defined points. The open circles denote points not included in the function on those segments, while the filled black circle at (1, -1) emphasizes its inclusion at that coordinate.
