Transcript text: For the following exercise, find $f^{-1}(x)$ for the function.
\[
\begin{array}{l}
f(x)=6-x \\
f^{-1}(x)=
\end{array}
\]
Solution
Solution Steps
To find the inverse of a function \( f(x) = 6 - x \), we need to swap the roles of \( x \) and \( y \) in the equation and solve for \( y \). This involves setting \( y = 6 - x \), then solving for \( x \) in terms of \( y \), and finally expressing \( x \) as a function of \( y \).
Step 1: Identify the Function
The given function is \( f(x) = 6 - x \).
Step 2: Swap Variables
To find the inverse, we swap \( x \) and \( y \) in the equation. Start with \( y = 6 - x \) and swap to get \( x = 6 - y \).
Step 3: Solve for the New Variable
Solve the equation \( x = 6 - y \) for \( y \):
\[
y = 6 - x
\]
Step 4: Express the Inverse Function
The inverse function is expressed as \( f^{-1}(x) = 6 - x \).
Final Answer
The inverse of the function is \(\boxed{f^{-1}(x) = 6 - x}\).
