Transcribed Image Text:**Title: Understanding Inverse Functions Using Graphical Analysis**
This educational resource explores the concept of inverse functions through graphical representation. Follow the steps below to learn how to sketch and analyze inverse functions:
### Task:
Use the graph of \( y = f(x) \) in (Figure 1 and Figure 2) to evaluate the following:
#### (a) Sketch the graph of \( y = f^{-1}(x) \)
- **Equation:** \(\frac{1 - (-3)}{2 - 0} = \frac{4}{2} = 2\)
- **Derivation:**
- Rewrite as \( y = \frac{x + 3}{2} \)
- Thus, \( f^{-1}(x) = \frac{x + 3}{2} \)
- **Graph Explanation:**
Two graphs are shown:
1. **Left Graph:** This is a linear graph depicting the function \( f^{-1}(x) \) passing through points (-3, 0) and (0, 1). This represents the line \( y = \frac{x + 3}{2} \), illustrating the inverse function.
2. **Right Graph:** This graph includes both \( f(x) \) and \( f^{-1}(x) \), indicating their relationship and symmetry about the line \( y = x \).
#### (b) Use part (a) to estimate \( f^{-1}(1) \)
- To estimate \( f^{-1}(1) \), observe the positions where the inverse graph intersects with \( y = 1 \).
These exercises demonstrate how to visualize and understand the functionalities and calculations related to inverse functions, essential for mathematical proficiency.

#### Figure 1: Graph of \( y = f(x) \)
The first graph depicts a linear function passing through the origin and extending from the third quadrant to the first quadrant. The line increases steadily with a positive slope, indicating a direct proportional relationship between \( x \) and \( y \).
- **X-Axis**: Extends from -4 to 4.
- **Y-Axis**: Extends from -4 to 4.
- **Key Characteristics**:
- The line crosses the y-axis at (0,0).
- The slope is positive, indicating an increasing function.
#### Figure 2: Graph of \( y = f(x) \)
The second graph illustrates a logarithmic curve, which appears to flatten out as \( x \) increases. It shows typical behavior of logarithmic growth:
- **X-Axis**: Extends from -4 to 4.
- **Y-Axis**: Extends from -4 to 4.
- **Key Characteristics**:
- The curve commences from the left and transitions from the third quadrant, gradually approaching the x-axis but never actually reaching negative values on the x-axis.
- The curve flattens as it moves to the right, indicative of slower rates of increase as \( x \) becomes larger.
These graphs provide insight into different types of mathematical functions, demonstrating linear vs. logarithmic relationships.
