One of the hardest things about learning the different exponential functions is knowing when to use each one.
I made this flowchart to help the students in our inclusion Algebra 2 class. Some didn't need it, others found it super helpful.
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 other types of exponential word problems. 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 to the half-life, appreciation and depreciation equations.
If you find that some of your students need a bit more help knowing when to use each function, you can find this flowchart in the sidebar "Freebies" section in the Exponential Functions folder.
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.
