Challenging Questions

I will be posting "Challenging" questions or "Thinking" questions usually found at the very end of each section in both precalculus textbooks. In terms of challenging or thinking questions, I will need the full solution (unless you think I can solve the problem given a few steps). I love challenging or thinking questions. Tough questions force students to demonstrate how much they have understood each section as a whole.

You say?

 

I think you can solve the problem with given a few steps. If you experience difficulties, I will provide step-by-step solution.

 

Ok. We will see if you are right. On my way to work now.
