### Lesson Structure
#### Introduction (10 minutes)
- **Warm-up Activity**: Quick review of prerequisite knowledge such as basic algebraic operations and simple functions. Use a few prompt questions to gauge understanding.
- **Objective Overview**: Briefly explain the topic for the day. Highlight the importance of advanced algebra in real-world applications and higher mathematics.
#### Direct Instruction (15 minutes)
- **Teaching New Content**:
- **Functions and Their Properties**: Define and explore different types of functions (linear, quadratic, polynomial) and their general forms.
- **Solving Advanced Equations**: Discuss methods such as factoring, using the quadratic formula, and synthetic division for higher-order polynomials.
- **Graphing Functions**: Show how to plot graphs of these functions, and identify intercepts, turning points, and any asymptotes.
- **Transformations**: Explain transformations including translations, reflections, stretches, and compressions.
#### Guided Practice (15 minutes)
- **Worked Examples**: Solve a few example problems together as a class, involving both solving equations and graphing functions. Encourage students to ask questions and participate.
- Example Problem 1: Solve the quadratic equation \( 3x^2 - 12x + 9 = 0 \).
- Example Problem 2: Graph the function \( f(x) = x^3 - 3x^2 + 2 \), identify its roots and turning points.
#### Independent Practice (15 minutes)
- **Practice Problems**: Distribute handouts with problems of varying difficulty. Students should work individually or in pairs to solve them, applying the methods discussed.
- Exercise Set:
1. Solve \( 4x^3 - x^2 - 7x + 10 = 0 \).
2. Transform the function \( g(x) = x^2 \) to \( h(x) = (x-2)^2 + 3 \) and graph both.
3. Identify and sketch the graph of \( f(x) = 1/(x-2) + 1 \).
#### Review and Recap (5 minutes)
- **Recap Key Points**: Summarise the main concepts covered in the lesson. Ensure students understand the steps involved in solving equations and graphing functions.
- **Q&A Session**: Address any remaining questions or areas of confusion.
### Homework/Extension Activity
- Assign homework problems that extend the day's learning:
- Solve additional equations from the textbook.
- Graph more complex functions.
- Explore real-world applications of algebraic functions, such as modelling.
#### Assessment/Evaluation
- Monitor student participation during guided practice.
- Review and provide feedback on independent practice handouts.
- Provide a short quiz in the next lesson to check understanding.
### Reflection
- After the class, evaluate which concepts were well understood and which ones need reinforcement.
- Note students who may need additional support and plan for differentiated instruction accordingly.
