Math Problem Statement
Given f(x), find g(x) and h(x) such that f(x)=g(h(x)) and neither g(x) nor h(x) is solely x.
f(x)=−2x3+4⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯√+2
Solution
To find functions and such that and neither nor is just , we need to analyze the given function:
Step 1: Identify
We want to identify an inner function such that the expression inside the square root is represented by . Let’s set:
Step 2: Identify
With , we can rewrite in terms of . Since , let’s define:
Verification
Now, substituting into : This matches , so the functions are correct.
Final Answer

Here are 5 related questions to consider:
- How would change if the constant outside the square root in was different?
- What if we used a different exponent for in ; how would that affect ?
- Can we choose multiple different and pairs for the same ?
- What types of functions work well with function composition, and why?
- How does function composition affect the domain and range of the resulting function?
Tip: When breaking down complex functions, start by identifying "outer" and "inner" parts to simplify composition.
