By the end of this lesson, you will be able to:
- Use function notation correctly.
- Evaluate and interpret functions from equations, graphs, and tables.
- Compare different types of functions and identify their characteristics.
- Describe relationships between variables using functions.
- Analyze function behavior using multiple representations.
A function describes a relationship in which each input corresponds to exactly one output. Functions can be represented by equations, graphs, tables, verbal descriptions, or real-world situations.
In previous lessons, you studied linear and quadratic functions separately. This lesson expands those ideas by introducing nonlinear functions, exponential functions, and systems involving multiple equations. Understanding how functions behave, change, and interact allows you to model real-world situations involving population growth, finance, engineering, science, and business.
Throughout this lesson, you will learn to evaluate functions, compare different function types, interpret graphs, solve systems involving nonlinear equations, and model practical situations using mathematical functions.
