As a business analyst reviewing forecasting models, you must correctly identify the mathematical functions used in the projections based on their formulas. What is the fundamental structural difference between an exponential function and a polynomial function?

A logistics manager is comparing two models for predicting the increase in shipping volume $V$ over time $t$. Model 1 follows a polynomial pattern ($V = t^2$), while Model 2 follows an exponential pattern ($V = 2^t$). Match each model type to the correct description of the variable $t$'s structural role in its formula.

A software engineer is categorizing algorithms based on their growth rates for a database update. They identify the function $f(n) = 2^n$ as an exponential function. True or False: This classification is correct because the variable $n$ serves as the exponent rather than the base.

An operations coordinator at a local delivery company is comparing two different models to predict package delivery volume over $t$ days. Model A is represented by the polynomial function $P(t) = t^3$, and Model B is represented by the exponential function $E(t) = 3^t$. In Model A, the variable $t$ serves as the base, whereas in Model B, the variable $t$ serves as the ____.
