IB MYP Math Investigation task Rational Function

IB MYP Key Concept:
Relationships: The task explores the relationship between time and the amount of water left in the washing machine. It also focuses on the behavior of the rational function as it approaches certain values, showing how changes in one variable (time) impact another (water volume).
Related Concepts:
Model: The rational function serves as a mathematical model that simulates a real-world process (draining water from a washing machine).
Change: The task explores how the quantity of water changes over time and how this change is represented in the graph of the rational function.
Global Context:
Scientific and Technical Innovation: This task connects to understanding scientific principles (like the rate of change in processes) and how mathematical modeling helps us understand real-world technical systems, such as household appliances.
Statement of Inquiry:
Mathematical models help us understand and represent changes in real-world systems over time, allowing us to predict and analyze behaviors such as water drainage in technological devices.
