Free Exponential Functions Flowchart

One of the hardest things about learning the different exponential functions is knowing when to use each one. I shared a graphing exponential functions cheat sheet the other day. The flowchart in this post is to help students identify which exponential function a word problem is asking them to use. Some of our Algebra 2 students didn't need it, others found it super helpful. 

Exponential Functions Flowchart for identifying exponential growth, decay, half-life and interest problems

The flowchart starts by asking students if their word problem mentions the word compounded. This is a good way to immediately differentiate between exponential word problems involving bank interest and the other types of exponential word problems.

I teach:

From there, one side of the flowchart leads students to the number of times interest is compounded per year while the other side of the flowchart moves into the half-life, appreciation and depreciation equations.

Later in the year we graph rational functions. During this unit, I find students need extra help with the steps. If you have found that graphing rationals is difficult for your students, you may like this post with a reference sheet for graphing rationals.
