Homework help...

I'll add videos to this post over the weekend, so pay attention as it grows!  Comment for questions or email me!

This video will help with completing the square.  This is needed for finding the inverse for #32 (when there are two x's and they have different powers).  I will help you solve this through a video of my own, but I thought you should at least try it on your own first!  Re-learn how to complete the square, then try it!  Completing the square will NOT be on the test.







WolframAlpha is awesome at finding inverse functions. If you stumble, ask them for a quick check!

Below are a few problems from Section 2.6.  If you have any other specific questions, please let me know and I'll make a new post!



Problem #33 from Section 2.6





Problem #35 from Section 2.6





Problem #36 from Section 2.6






Problem #29 from Section 2.7 on inverse functions






Problems #53-55 from Section 2.6 on inverse functions
