What is a mathematical model? Explain this statement: A model's predictions can only be as good as the data and the assumptions from which the model is built.Choose the correct answer below.*****A. Mathematical models are based on relationships between quantities that remain constant and are described by mathematical tools called functions.B. Mathematical models are based on relationships between quantities that change and are described by very complicated functions that can only be understood using supercomputers.C. Mathematical models are based on relatickships between quantities that remain constant and can only be described by a graph.D. Mathematical models are based on relationships between quantities that change and are described by mathematical tools called functions.
