Original Promptdomain and range of graphs
This learning resource focuses on the concept of domain and range for both discrete and continuous functions. Students will learn to determine the set of possible input values (domain) and output values (range) from graphs, using inequality and interval notation. The document includes worked examples for different types of functions such as a discrete set of points, continuous line segments, and a continuous curve (parabola). Additional practice variations are provided to analyze the effects of open versus closed circles on endpoints. Challenge problems further explore complex behaviors, including circular patterns and piecewise functions, helping students understand the nuances in determining domain and range.
