N w Output Get the Gizmo ready: Activity A: Click Clear all . . Be sure Show mapping diagram, Show ordered Relations pairs, and Show graph are selected. 1. Consider this relation: (1, 5), (4, 2), (3, 1), and (2, 4). A. First, click inside the Show ordered pairs box, type (1, 5), and hit Enter. According to this ordered pair, what is the output of this relation when the input is 1? B. In the Gizmo, type in the other three ordered pairs. The set of all input (x) values form the domain of a relation. The set of all output (y) values form the range. How can you determine the domain and range from the mapping diagram? C. What are the domain and range of this relation, from smallest to largest? Domain: Range: { 2. Click Clear all. Create a graph with 5 points whose domain is {2, 4, 5}. Input Output A. Record the coordinates of your points in the table to the right. B. What is the range of your relation? C. Look at the mapping diagram in the Gizmo. If a relation has more numbers in its range than in its domain, like this one does, what has to be true? 3. Consider this relation: If the input is 3, the output is 5. If the input is 2, the output is 2. If the input is 1, the output is 4. If the input is 4, the output is 5. First, sketch the relation's mapping diagram, ordered pairs, and graph below. Then create it in the Gizmo to check your answer. Input Output Ordered pairs (x, y) 2 2 Output N 3 3 4 2 3 4 5 Input 5 Sort Export Drag points to graph Reproduction for educational use only.
