Common Core: High School - Functions

This subject covers the essential concepts and applications of functions in high school mathematics, preparing students for advanced mathematical reasoning.

Practical Applications

Functions in Finance

Using Functions to Understand Money

Functions are used everywhere in finance! They help calculate things like interest, savings, and investments.

Simple Interest

The formula \( I = Prt \) is a function that calculates interest earned (\( I \)) based on principal (\( P \)), rate (\( r \)), and time (\( t \)).

Compound Interest

Compound interest uses exponential functions: \( A = P(1 + r/n)^{nt} \).

Making Smart Choices

Understanding these functions helps you make better decisions about saving, spending, and investing.

Examples

  • Calculating how much money you'll have after 5 years in a savings account.

  • Comparing different loan offers by modeling payments using functions.
