I have been having trouble with htis problem for a while, nad my teacher won't give me any feedback on the problem. This is a huge part of my grade so it is important, and I wondering if I could receive help? Here is the problem: Imagine that you live on an infinitely long and straight street called Infinite Drive. The addresses on Infinite Drive are given by real numbers. Your address on the street is π while your friend Patrickβs is β3 and Karenβs is sin60Β°. There are two moving companies, π and π. Those companies move people along Infinite Drive from address π₯ to new addresses π(π₯) or π(π₯), depending on which company people choose. Assume that the functions π(π₯) = 1 β π₯ and π(π₯) = 1 π₯ describe how the moving companies move people from one address to another. a. Find π(π(π₯)) and π(π(π₯)). b. Evaluate your answers from a for π₯ = π, your address. c. Evaluate your answers from a for π₯ = 0, your parentsβ address. Explain the significance of this answer. 2. Now assume that the moving companies are described by the functions π(π₯) = 5π₯ and π(π₯) = 1 π₯ . a. Find π(π(π₯)) and π(π(π₯)). b. Evaluate your answers from a for π₯ = π, your address. 3. Notice that the functions in Part 1 have the property that π = πβ1 and π = πβ1. That is, the inverse of π is equal to itself and the inverse of π is also equal to itself. Take the composition of each function with itself to show that this is true. Remember, if the function β(π₯) is equal to its own inverse, then β β ββ1 = π₯.

I don't think your specification for $g(x)$ came through correctly. It would help if you split things into paragraphs as well.

This problem requires me to spend some time thinking about things and I'm unwilling to do that. My teacher wouldn't give me the answer so I hope someone here will. Is that about right?
