Step 1 :We are given two pairs of functions and we are asked to find the composition of these functions and determine if they are inverses of each other.
Step 2 :For the first pair, we have \(f(x) = \frac{4}{x}\) and \(g(x) = \frac{4}{x}\). To find \(f(g(x))\) and \(g(f(x))\), we need to substitute \(g(x)\) into \(f(x)\) and vice versa.
Step 3 :For the second pair, we have \(f(x) = 6x + 1\) and \(g(x) = 6x - 1\). Similarly, we need to substitute \(g(x)\) into \(f(x)\) and vice versa.
Step 4 :Two functions are inverses of each other if and only if \(f(g(x)) = x\) and \(g(f(x)) = x\) for all \(x\) in their domains.
Step 5 :Let's start with the first pair of functions. After substitution, we find that \(f(g(x)) = x\) and \(g(f(x)) = x\). This means that \(f\) and \(g\) are inverses of each other for the first pair.
Step 6 :Now, let's move on to the second pair of functions. After substitution, we find that \(f(g(x)) = 36x - 5\) and \(g(f(x)) = 36x + 5\). This means that \(f\) and \(g\) are not inverses of each other for the second pair because \(f(g(x)) \neq x\) and \(g(f(x)) \neq x\).
Step 7 :\(\boxed{\text{Final Answer: For the first pair of functions, } f \text{ and } g \text{ are inverses of each other. For the second pair of functions, } f \text{ and } g \text{ are not inverses of each other.}}\)
