What is the difference between a piecewise function and a polynomial function?
To evaluate a piecewise function, you need to identify the relevant sub-function by checking the input value against the interval specified in the function definition. This may involve checking for equality, inequality, or other mathematical relationships.

A piecewise function is a mathematical function that is defined by multiple sub-functions, each applied to a specific interval of the function's domain. This allows piecewise functions to model complex, non-linear relationships between variables. To evaluate a piecewise function, you need to identify the relevant sub-function and apply the appropriate mathematical operations. For example, consider the piecewise function:
How do I determine which sub-function to use for a given input?
A polynomial function is a function that can be written in the form f(x) = ax^n + bx^(n-1) +... + c, where a, b,..., c are constants. In contrast, a piecewise function is defined by multiple sub-functions, each applied to a specific interval of the domain.
