Inside Collection: Advanced Algebra II: Activities and Homework
Summary: This module provides a practice problem designed to lead students through a typical TAPPS problem: solving for y in an inverse function.
OK, so you’re looking for the inverse function of
First of all, let’s review what that means! To “solve it for y” means that we have to get it in the form
“Solving it for
So that’s our goal. How do we accomplish it?
1. The biggest problem we have is the fraction. To get rid of it, we multiply both sides by


2. Now, we distribute through. 

3. Remember that our goal is to isolate


4. Now comes the key step: we factor out a


5. Finally, we divide both sides by what is left in the parentheses! 

Tada! We’re done!
Test 1:
Test 2:
Now, you try it! Follow the above steps one at a time. You should switch roles at this point: the previous student should do the work, explaining each step to the previous teacher. Your job: find the inverse function of
