# AFA.FGR.3: Functions in Financial Contexts

Explore and apply functions to model and explain real-life phenomena and to solve complex problems in business and financial contexts.

- Subject: Mathematics
- Appears in: High School, https://georgiahomeroom.org/standards/math/high-school.md

## Expectations

- **AFA.FGR.3.1**: Examine and identify the key characteristics of functions that model financial situations given the parameters of the context.
- **AFA.FGR.3.2**: Solve financial problems given the parameters of the applicable context using a variety of functions.
- **AFA.FGR.3.3**: Describe the meaning of functions and how to determine if a relation is a function or not.
- **AFA.FGR.3.4**: Utilize function notation to represent a functional relation and to evaluate functions.
- **AFA.FGR.3.5**: Create, apply, and interpret linear functions to model real-world financial problems.
- **AFA.FGR.3.6**: Create, apply, and interpret exponential functions of the form y = $ab^x$ and classify them as exponential decay (when 0 < b < 1) or as exponential growth (when b > 1).
- **AFA.FGR.3.7**: Create, apply, and interpret quadratic functions to model real-world financial applications.
- **AFA.FGR.3.8**: Create, apply, and interpret the greatest integer function in real-world financial applications.
- **AFA.FGR.3.9**: Create, apply, and interpret piecewise functions in real-world financial applications.
- **AFA.FGR.3.10**: Recognize real-world situations where square root, cubic, or rational functions apply.
- **AFA.FGR.3.11**: Create and use inequalities to define domains when creating algebraic expressions and functions.
