Example: Finding the Inverse of the Function $f(x) = 4x + 7$

Example: Finding the Inverse of the Function $f(x) = 5x - 3$

Example: Finding the Inverse of the Function $f(x) = 8x + 5$

In professional roles such as logistics, inventory management, or financial analysis, you often need to reverse a mathematical formula to find an input value from a known output. This involves finding an inverse function. Arrange the following steps in the correct algebraic order to find the inverse of a one-to-one function $f(x)$.

A business analyst uses a one-to-one function $f(x)$ to model the relationship between advertising spend and total revenue. To determine the advertising spend required to reach a specific revenue goal, the analyst must find the inverse function. When following the standard five-step algebraic process to find this inverse, which step specifically represents the act of swapping the function's domain and range?

In technical roles such as financial modeling or data science, accuracy is confirmed through specific verification steps. In the standard five-step algebraic process for finding the inverse of a one-to-one function $f(x)$, the final step is to verify the result by checking that the composition of the function and its inverse, $f(f^{-1}(x))$, simplifies to the identity value $x$.

In technical careers such as engineering or data analysis, reversing a mathematical process is essential for troubleshooting and forecasting. Match each step of the standard five-step algebraic process for finding the inverse of a one-to-one function $f(x)$ with its specific action.

Reversing a Revenue Model

A logistics coordinator is analyzing a delivery schedule model defined by a one-to-one function. To reverse the model to calculate time based on distance, they follow the standard five-step process to find the inverse function algebraically. In the second step, they interchange the variables $x$ and $y$. This specific action algebraically represents swapping the function's domain and _____.
