Math Problem Statement
Solution
To determine whether the functions and are inverses, we can check if and . Let's compute these one by one.
-
Check :
- First, substitute into : Simplify this expression step by step.
-
Check :
- Next, substitute into : Simplify this to see if the result is .
I'll now compute both expressions to verify whether the functions are inverses.The computations yield the following results:
Since neither simplifies to nor simplifies to , the functions and are not inverses of each other.
Therefore, the correct answer is False.
Would you like more details on any part of the process? Here are some follow-up questions for further practice:
- What does it mean for two functions to be inverses in general?
- How can you algebraically derive the inverse of a given function?
- Why is verifying and necessary to confirm that functions are inverses?
- Can a function always have an inverse?
- What would the graph of two inverse functions look like?
Tip: When finding the inverse of a function, remember to swap and and solve for .
