This subject covers the essential concepts and applications of functions in high school mathematics, preparing students for advanced mathematical reasoning.
Functions are used everywhere in finance! They help calculate things like interest, savings, and investments.
The formula \( I = Prt \) is a function that calculates interest earned (\( I \)) based on principal (\( P \)), rate (\( r \)), and time (\( t \)).
Compound interest uses exponential functions: \( A = P(1 + r/n)^{nt} \).
Understanding these functions helps you make better decisions about saving, spending, and investing.
