A small business owner uses the function $f(x) = 4x - 5$ to represent the average cost per item and $g(x) = 2x + 3$ to represent the number of items sold. Which of the following expressions shows the correct setup to find the total revenue function, $(f \cdot g)(x)$, before it is simplified?

A colleague in your financial analysis team asserts that the notation $(f \cdot g)(x)$ means you should substitute the output of function $g$ as the input into function $f$. Is this statement true or false?

A business analyst is modeling total revenue by multiplying a unit price function $f(x) = 4x - 5$ and a quantity function $g(x) = 2x + 3$. To find the total revenue function $(f \cdot g)(x)$, the analyst must follow a specific sequence of algebraic steps. Arrange the following steps in the correct order to determine the final simplified product polynomial.

A retail analyst uses the function $f(x) = 4x - 5$ to represent the profit margin per unit and $g(x) = 2x + 3$ to represent the daily sales volume. To prepare a correct financial model, the analyst must distinguish between different function operations. Match each mathematical expression with its correct description based on these two functions.
