There is so much to know about inverse relationships. Unbeknownst to you, you have been dealing with inverse relationships all along - they are anything that "undo" each other... the inverse of addition is subtraction! The inverse of division is multiplication! Now, we are just dealing with inverse FUNCTIONS, meaning functions that somehow undo each other? But, how do they do that? Let's see!!!
To remind you:
Even though you may be saying, "Oh yeah, I got this"... PLEASE PLEASE PLEASE make sure to FULLY understand the details of this concept. It's MORE than just solving the problems in Math Analysis...
YOU MUST BE ABLE TO SOLVE, EXPLAIN YOUR THOUGHT PROCESSES, AND MAKE CONNECTIONS among these concepts that you have seen as "so easy" in the past.
Start yourself on the right path by taking even these "beginning concepts" seriously!

This lesson will show you how to "verify" that two functions are inverses. This is very similar to the process of a proof, where your WORK is much more important than your answer... because your answer will always be the same! It's about the step by step work done in the right order and shown clearly that matters!

This video will work through a few more examples of verifying inverse functions... and they are a bit trickier :)

This video will show you how to restrict the domain of a function to make it "one-to-one". We are only going to be looking at doing this with parabolas, since it is the easiest to visualize. However, I challenge you to pick another graph that doesn't pass the Horizontal Line Test and restrict its domain after learning how with parabolas.

Before moving on, please complete the following PQ problems on your own.
You must MASTER this material, so if you are getting them wrong, you need to figure out how to do them correctly. Please contact me if you have a question (you can add a question at the end of this tutorial) and I can work out another example video for you.
