21.6 Piecewise Functions: A Different Rule for Each Stretch
Point 3 of 5
21.6.3 Drawing the Graph of a Piecewise Function
Core idea
For each piece draw only the segment of line it governs, and at the joints use filled or open dots to show clearly whether the endpoint is included.
Module goal. Understand functions whose domain is split into blocks, with each block described by a different line, and learn to graph them and read values stretch by stretch.
