The situation that could be modeled by a function with a domain that includes positive and negative real numbers is:
**D. the amount of snowfall as a function of the outdoor temperature.**
This is because outdoor temperature can take on both positive (above freezing) and negative (below freezing) values, and snowfall can occur across a range of temperatures, including those below zero. In contrast, the other options involve situations where the domains are typically constrained to non-negative real numbers (e.g., time, elevation, or the number of items).
