It looks like you're looking for help with a lesson or unit test focused on function analysis. While I can't provide specific test questions or answers, I can offer an overview of concepts related to function analysis that are commonly covered in such lessons. Here are a few key topics that might be included:
### Key Concepts in Function Analysis
1. **Understanding Functions**:
- Definition of a function: a relation in which each input has exactly one output.
- Different types of functions (linear, quadratic, polynomial, rational, exponential, logarithmic, etc.).
2. **Domain and Range**:
- Domain: all possible input values (x-values) for a function.
- Range: all possible output values (y-values) for a function.
3. **Graphing Functions**:
- How to plot functions on a graph.
- Understanding intercepts (x-intercepts and y-intercepts).
- Identifying increasing, decreasing, and constant intervals.
4. **Function Behavior**:
- Asymptotes: vertical and horizontal asymptotes for rational functions.
- End behavior of functions: how the function behaves as x approaches positive or negative infinity.
5. **Transformations of Functions**:
- Vertical and horizontal shifts.
- Reflections over axes.
- Stretching and compressing functions.
6. **Zeros of a Function**:
- Finding zeros (or roots) of a function analytically or graphically.
- The importance of the zeros in the context of the function.
7. **Using Function Notation**:
- Understanding and applying function notation (e.g., f(x)).
- Evaluating functions for given input values.
8. **Applications of Functions**:
- Real-world applications, including modeling with functions.
- Using functions to solve problems in various contexts.
### Sample Types of Questions
1. Given a function \( f(x) = ax^2 + bx + c \), determine the vertex of the parabola it represents.
2. For the function \( g(x) = \frac{1}{x-3} \), identify the vertical and horizontal asymptotes.
3. Graph the function \( h(x) = |x - 2| + 1 \) and determine its vertex.
4. Find the domain and range of the function \( j(x) = \sqrt{x + 4} \).
5. Write a brief explanation of how a transformation impacts the graph of a function, providing an example.
If you have specific questions or concepts you'd like to delve into related to function analysis, feel free to ask!
