# Algebra II

Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. In algebra 2 we build upon that foundation and not only extend our knowledge of algebra 1, but slowly become capable of tackling the BIG questions of the universe. We'll again touch on systems of equations, inequalities, and functions...but we'll also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices. Don't let these big words intimidate you. We're on this journey with you!

## Exponential growth and decay

From compound interest to population growth to half lives of radioactive materials, it all comes down to exponential growth and decay.

## Modeling with exponential functions

As we'll see in this tutorial, anything from compound interest to radioactive decay can be modeled with exponential functions.

## Logarithmic functions

This tutorial shows you what a logarithmic function is. It will then go on to show the many times in nature and science that these type of functions are useful to describe what is happening.

## Logarithmic equations

Now that you are familiar with logarithms and logarithmic functions, let's think about how to solve equations involving logarithms.

## Continuous compounding and e

This tutorial introduces us to one of the derivations (from finance and continuously compounding interest) of the irrational number 'e' which is roughly 2.71...
