Multivariable polynomial functions

Multivariable polynomial functions are mathematical formulas that involve two or more variables raised to various powers and combined through addition, subtraction, and multiplication. Think of them as formulas that relate multiple factors—like height and weight—to produce an outcome, such as health score. Unlike simpler formulas with just one variable, these capture complex relationships between several factors at once. For example, a function might take height and age to predict a person's risk of a certain condition. They are useful in fields like engineering, science, and economics to model and analyze systems influenced by multiple variables simultaneously.
