Math Problem Statement
Solution
The question is asking to find the correct pair of functions and such that , and given that .
We need to find the functions and that, when composed as , give the function .
Start by analyzing the structure of : This resembles the form of a composition where:
- Inside the square root is , which suggests .
- The outer function is , which suggests .
Thus, we have the functions:
Looking at the provided options, the correct choice is the third one:

- What is the definition of function composition in mathematics?
- How do you determine the functions and in a composite function?
- What is the domain of in this example, given the square root function involved?
- How would the graph of compare to the graphs of and ?
- Can function composition always be reversed to find and from ?
Tip: When working with composite functions, always check the domain of the inner function, as it can affect the domain of the overall composition.
