# Algebra 1 - Exponential Functions

An exponential function is a function where the unknown is appearing in the exponent. The form is f(x)=abx, where aâ‰ 0 , bâ‰ 1 and b>0.  Basically, they are used to show instances when a constant change in the independent variable gives the same proportional change in the dependent variable. In today's free Algebra 1 video on Exponential Functions, you'll see several real world examples to teach this concept because often these functions are used to model real world things. Find out how you can utilize exponential functions to determine the squirrel population in 5 years! You will also learn how to determine if a set of ordered pairs satisfies an exponential function and how to identify and graph an exponential function.

Professor Burger was just recently featured in an article in The Chronicle of Higher Education. We are excited that they did a profile on him and his love of teaching math. Even if you feel you know all about Edward Burger, you should read this article, as there are all sorts of interesting facts about his path into teaching. It's an inspiring article that makes me wish I could have taken one of his math classes in college.
