2. Understand and manipulate functions.
3. Graph and interpret advanced algebraic functions.
#### Materials Needed
- Whiteboard and markers
- Graphing calculators or graphing software
- Student handouts with problems
- Graph paper
- Projector and screen (optional for visual aids)
#### Introduction (10 minutes)
1. **Greeting and Attendance:** Welcome students and take attendance.
2. **Review of Previous Lesson:** Briefly review key concepts from the previous lessons on basic algebra.
3. **Objective Overview:** Introduce the objectives for today's lesson on advanced functions and equations.
#### Direct Instruction (15 minutes)
1. **Advanced Linear Equations:**
- Briefly recap how to solve simple linear equations.
- Introduce advanced linear equations that include fractions and variables on both sides. Example:
\[ \frac{2x + 3}{4} - \frac{x}{3} = 5 \]
- Solve the example step by step on the whiteboard.
2. **Quadratic Equations:**
- Review the standard form of a quadratic equation \( ax^2 + bx + c = 0 \).
- Introduce methods for solving such as factoring, completing the square, and the quadratic formula.
- Solve an example using the quadratic formula:
\[ 2x^2 - 4x - 6 = 0 \]
- Discuss the meaning of the results (real and imaginary solutions).
3. **Functions:**
- Define what a function is and denote function notation \( f(x) \).
- Discuss different types of functions: linear, quadratic, and polynomial.
- Explain the concepts of domain and range.
#### Guided Practice (15 minutes)
1. **Function Manipulation:**
- Provide practice problems that involve evaluating functions for given values.
- Example: If \( f(x) = 2x^2 - 3x + 1 \), find \( f(2) \) and \( f(-1) \).
2. **Graphing Functions:**
- Plot basic linear and quadratic functions on graph paper or using graphing software.
- Example: Graph \( y = x^2 - 4x + 3 \).
- Discuss key features such as intercepts, vertex, and axis of symmetry.
3. **Solving Quadratic Equations:**
- Provide worksheets with quadratic equations to be solved using different methods.
- Work through a couple of problems together.
#### Independent Practice (10 minutes)
1. **Worksheets:**
- Distribute worksheets with a mix of linear and quadratic equations, as well as function evaluation and graphing problems.
- Encourage students to work independently, but be available for questions.
#### Conclusion (5 minutes)
1. **Review and Recap:**
- Ask students to share some of their solutions and explain their thought process.
- Summarize the key points of the lesson: solving advanced equations and understanding functions.
2. **Homework Assignment:**
- Assign practice problems from the textbook or a handout for further practice at home.
- Notify students of any upcoming quizzes or assessments related to the topic.
3. **Closing and Questions:**
- Open the floor for any last questions or concerns from students.
#### Assessment
- **Formative:**
- Observe students as they work on guided practice problems to check for understanding.
- Collect and review independent practice worksheets to assess individual progress.
- **Summative:**
- Evaluate homework and conduct a quiz in the following lesson to assess comprehension and mastery of the topics.
#### Differentiation Strategies
- Provide additional resources or simplified problems for students who need extra help.
- Offer challenging problems or extension activities for advanced students.
- Utilize visual aids and interactive tools for better engagement and understanding.
