Example 1
Is {(3, 4), (4, 5), (5, 6), . . .} a relation?
Example 2
Is {(1, 2), (2, 5, 17), (4, 5)} a relation?
Example 3
Is {(1, 1)} a relation?
Example 4
Find the domain and range for the following relation. Remember that each element of a set need only be listed once.
{(1, 1), (2, 1), (3, 1)}
Example 5
Find the domain and range for the following relation. Remember that each element of a set need only be listed once.
{(1, 3), (2, 4), (3, 5), (4, 6) , . . .}
Example 6
Find the domain and range for the following relation. Remember that each element of a set need only be listed once.
{(a, b), (c, d), (e, c)}
Example 7
For the following relation, write an equation that describes the connection between x (the first number in an ordered pair) and y (the second number in an ordered pair).
{(1, 1), (1, -1), (4, 2), (4, -2), (9, 3), (9, -3)}
Example 8
For the following relation, write an equation that describes the connection between x (the first number in an ordered pair) and y (the second number in an ordered pair).
{(1, 4), (2, 3), (3, 2), (4, 1), (5, 0), (6, -1), (7, -2)}
Example 9
Find the relation described: x + y = 6 and x is an integer between 4 and 7.
Example 10
Find the relation described: |x| = y. Remember that absolute value thing from way back when?
