Key Concepts

Continuity and Discontinuity

When graphing piecewise functions, it is important to analyze the continuity at the boundaries where the function definitions change. Discontinuities may arise if the function values do not align at these boundaries, and these must be clearly indicated on the graph to reflect the function's true behavior.

Domain and Intervals

Understanding the domain is essential when working with piecewise functions, as each segment is defined over a specific set of input values. Recognizing these intervals helps in correctly aligning each piece of the function to its corresponding portion of the graph.

Piecewise Functions

A piecewise function is defined using different expressions over distinct intervals of its domain. This allows for a function to have different behaviors in different sub-domains, making them useful for modeling situations where the rule or behavior changes at specific points.

Graphing Piecewise Functions

Graphing a piecewise function involves plotting each segment of the function over its designated interval, while carefully indicating the endpoints. This often requires distinguishing between included endpoints (typically marked with a solid dot) and excluded endpoints (marked with an open dot) to accurately represent the function's definition.
