1: DOMAIN AND RANGE FROM TABLES, SET OF POINTS AND DIAGRAMS

1. Given the table: 

x -5 -1 0 0 1 2
y 1 4 9 11 13 20
The domain is the set of all x's: {5, -1, 0, 1, 2}
The range is the set of all y's: {1, 4, 9, 11, 13, 20}

2. Given the set of points: 

 (-2, 3), (-1,4), (0,5), (0,6), (1, 7), (2, 8) The domain is the set of all x's: {5, -1, 0, 1, 2}
The range is the set of all y's: {1, 4, 9, 11, 13, 20}

3. Given the diagram: 

 Relation Diagram The domain is the set of all x's: {-2, -1, 0, 1, 2}
The range is the set of all y's: {3, 4, 5, 6, 7, 8}

CONCEPT CHECK: What is the maximum value of the range of the function from the following list:
