Compound Interest as Exponential Growth
When a principal of dollars is invested at an annual interest rate (expressed as a decimal) compounded times yearly, the amount after years follows an exponential growth model: Key formulas include expressions such as P. This concept is part of Big Ideas Math, Algebra 2 for Grade 8 students, covered in Chapter 6: Exponential and Logarithmic Functions.
Key Concepts
When a principal of $P$ dollars is invested at an annual interest rate $r$ (expressed as a decimal) compounded $n$ times yearly, the amount $A$ after $t$ years follows an exponential growth model: $$A = P\left(1 + \frac{r}{n}\right)^{nt}$$.
This is an exponential function of the form $A = P \cdot b^{nt}$ where the base $b = 1 + \frac{r}{n} 1$.
