Piecewise defined functions are mathematical entities that are described by different expressions over various intervals within their domain
Piecewise functions are essential for accurately modeling situations where a single expression cannot capture the behavior of a variable throughout the entire domain
Piecewise functions can exhibit both continuous and discontinuous behavior, making them highly adaptable for use in diverse disciplines such as physics, economics, and engineering
The domain of a piecewise function is partitioned into subintervals, with a distinct mathematical expression assigned to each
Transition points, or break points, are the values at which the function's rule changes
Graphing piecewise functions involves plotting each segment on a coordinate plane and denoting break points with appropriate markers
To graph a piecewise function, one must follow a structured approach of graphing each segment individually and then synthesizing them to form the complete graph
To evaluate a piecewise function at a specific input, one must first identify the relevant interval and apply the corresponding expression to calculate the output
Piecewise functions are employed in various disciplines, such as economics, engineering, and computer science, to model complex, variable-dependent situations
