# Year 11 Mathematics Lesson Plan: Advanced Algebra (Functions and Equations)
### Objective:
By the end of this lesson, students will be able to:
1. Understand and apply properties of advanced algebraic functions.
2. Solve complex algebraic equations, including polynomial, exponential, and logarithmic equations.
3. Analyze and interpret functions graphically and algebraically.
### Common Core Standards:
- HSF-IF.B.4: For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities.
- HSA-SSE.B.3: Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression.
### Materials Needed:
- Graphing calculators
- Whiteboard and markers
- Projector or interactive whiteboard
- Handouts with practice problems
- Textbooks/Reference materials
