An inventory management system uses a function $P(n)$ to calculate the total price of $n$ items. When the system needs to determine the number of items based on a total price, the documentation refers to the inverse function $P^{-1}(x)$. In this notation, what is the primary purpose of the superscript $-1$?

A financial model uses the function $R(x)$ to project weekly revenue based on $x$ units sold. If a business analyst sees the notation $R^{-1}(x)$ in the model's documentation, this indicates the reciprocal of the revenue function, meaning they should calculate $\frac{1}{R(x)}$.

A warehouse logistics manager uses a function $W(n)$ to calculate the total weight of a shipment based on the number of units $n$. To find the number of units when the weight is known, the manager uses the inverse function. Match each part of the inverse notation with its correct description or meaning.

A logistics coordinator uses a function $T(d)$ to determine the time required for a truck to travel a distance $d$. To calculate the distance that can be covered given a specific amount of time, the coordinator uses the notation $T^{-1}(y)$. In this mathematical notation, the superscript $-1$ is a specialized symbol indicating that $T^{-1}$ is the ____ function.
