Sure! I can help you prepare for a unit test on functions and their graphs. Below are some potential topics and questions that may be included in such a test:
### Topics to Review
1. **Types of Functions**: Linear, quadratic, polynomial, rational, exponential, logarithmic, trigonometric, etc.
2. **Function Notation**: Understanding how to read and write functions using function notation \( f(x) \).
3. **Domain and Range**: Finding the domain and range of various functions.
4. **Intercepts**: Finding x-intercepts and y-intercepts.
5. **Transformations of Functions**: Shifting, reflecting, stretching, and compressing graphs.
6. **Composition of Functions**: Calculating and understanding the composition \( (f \circ g)(x) \).
7. **Inverse Functions**: Finding the inverse of a function and understanding its graph.
8. **Graphing Functions**: Plotting points and sketching their graphs accurately.
9. **Asymptotes and Behavior at Infinity**: Finding horizontal and vertical asymptotes and understanding end behavior.
10. **Piecewise Functions**: Evaluating and graphing piecewise-defined functions.
### Sample Questions
1. **Identify the Function Type**:
- Is \( f(x) = 2x^2 - 4x + 1 \) a linear, quadratic, polynomial, or another type of function?
2. **Find Domain and Range**:
- Determine the domain and range of \( f(x) = \frac{1}{x-3} \).
3. **Intercepts**:
- Find the x-intercept(s) and y-intercept of \( f(x) = x^2 - 5x + 6 \).
4. **Graph Transformation**:
- Describe the transformations of \( g(x) = f(x - 3) + 2 \) where \( f(x) \) is the basic function \( f(x) = x^2 \).
5. **Composition of Functions**:
- Given \( f(x) = 3x + 1 \) and \( g(x) = x^2 \), find \( (f \circ g)(x) \) and \( (g \circ f)(x) \).
6. **Find the Inverse**:
- Find the inverse of the function \( f(x) = 2x - 5 \).
7. **Graphing a Function**:
- Sketch the graph of \( f(x) = |x - 2| + 3 \).
8. **Behavior at Infinity**:
- Determine the end behavior of the function \( f(x) = -2x^3 + x^2 + 4 \).
9. **Piecewise Function Evaluation**:
- Evaluate the piecewise function \( f(x) = \begin{cases}
x^2 & \text{if } x < 0 \\
2x + 1 & \text{if } x \geq 0
\end{cases} \) for \( x = -3 \) and \( x = 2 \).
10. **Asymptotes**:
- Find the vertical and horizontal asymptotes of the function \( g(x) = \frac{2x + 1}{x^2 - 4} \).
### Practice Problems
- Graph the function \( f(x) = \sqrt{x + 2} - 1 \) and identify key features such as the vertex and intercepts.
- Given the function \( f(x) = 3\sin(x) \), describe its amplitude, period, and graph one complete cycle.
