### Understanding Graphical Representation of Functions
#### Graph Description
The graph displayed on this page represents a mathematical function depicted in the Cartesian coordinate system with the x-axis (horizontal) and y-axis (vertical).
- The x-axis ranges from -2 to 5.
- The y-axis ranges from -2 to 4.
#### Key Features of the Graph
1. **Axes and Scale**:
- The x-axis is labeled with values from -2 to 5.
- The y-axis is labeled with values from -2 to 4.
- Both axes intersect at the origin (0,0).
2. **Graph Behavior**:
- There is a vertical asymptote at \( x = -2 \).
- The function decreases towards negative infinity as it approaches \( x = -2 \) from the right.
- At \( x = 0 \) and \( x = 2 \), there are open circles indicating discontinuities in the function.
- The function value at \( x = 0 \) is approaching 2 from the left and right.
- The function decreases to a minimum at \( x = 2 \) and then increases again, forming a valley shape.
- At \( x = 4 \), the function has a closed circle hovering at \( y = 3.5 \).
3. **General Shape**:
- The graph shows peaks and valleys, indicating it is not a linear function.
- The leftmost part of the graph starts at the top moving downwards steeply.
- After the drop past \( x = -2 \), the graph increases steeply, moving through a valley.
- Finally, there is a sharp increase with another steep incline starting from just before \( x = 5 \).
4. **Discontinuities**:
- There are distinct points of discontinuity at \( x = 0 \) and \( x = 2 \) where the function has open circles.
- The value of the function at \( x = 4 \) extends with an open circle indicating a defined y-value for that x-coordinate.
#### Summary
This graph displays multiple characteristics such as asymptotes, discontinuities, and varying slopes. Understanding these elements helps in grasping the behavior of complex functions, particularly in evaluating limits and continuity.
