Math Problem Statement
Solution
The problem asks to find two functions, and , such that their composition , where . The additional condition is that neither function can be the identity function.
To solve this, we need to decompose the function into a composition of two simpler functions.
Decomposition Approach:
One possible decomposition is:
- Let , which simplifies part of the expression.
- Then, let .
Now let's check this:
- If , then applying to gives:
Thus, , as required.
Final Answer:
This is one possible solution, but there may be other valid decompositions as well.
