A piecewise function is defined by multiple sub-functions, each applying to a specific interval of the domain. It allows for different behaviors over different parts of the domain.

Piecewise functions are often used to model situations where a rule changes based on the input value.
The domain of a piecewise function is the union of the domains of its sub-functions.
Each sub-function in a piecewise function has its own formula and interval.
When graphing a piecewise function, you plot each sub-function over its specified interval and check for continuity at the boundaries.
To evaluate a piecewise function, determine which sub-function applies to the given input value.
A way of writing subsets of the real number line using intervals. It uses brackets and parentheses to describe whether endpoints are included or excluded.
